Description

Technical Field

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

[0002] There are generally two ways to release pressure after cooking in existing pressure cooking appliances. One is manual pressure release, which requires the user to manually operate the pressure release valve to lift it and release the air. The other is automatic pressure release, which involves installing a solenoid valve on the lid. The solenoid valve is automatically operated by electrical control after cooking, extending the valve stem to push the valve rod, thereby causing the valve stem to avoid the vent.

[0003] After cooking, turn the lid handle to separate the lid teeth from the pot teeth, thus opening the lid. However, because the valve stem and solenoid valve are misaligned at this time, the solenoid valve cannot push the valve stem, meaning the valve stem will block the vent again. When the lid is closed again, the pressure inside the pot will increase because the vent is blocked by the valve stem, which can easily cause danger for the user. Utility Model Content

[0004] The main objective of this invention is to provide a lid assembly and a cooking appliance having the same, in order to solve the problem in related technologies where the vent is blocked after the lid is opened, which can easily lead to danger.

[0005] To achieve the above objectives, according to one aspect of the present invention, a cover assembly is provided, comprising: a liner having a mounting hole; a pressure-bearing cover rotatably disposed below the liner, the pressure-bearing cover having a locked position and an unlocked position; a pressure-relief structure connected to the pressure-bearing cover and extending through the mounting hole from the liner, the pressure-relief structure rotating synchronously with the pressure-bearing cover, the pressure-relief structure including a valve body and a valve core structure, the valve body having a valve cavity and an inlet and an outlet communicating with the valve cavity, the valve core structure including a connecting structure and a sealing element disposed on the connecting structure, the sealing element being correspondingly disposed with the outlet; a reset element drivingly cooperating with the connecting structure to keep the sealing element in the position of blocking the outlet; and a stop top disposed on the liner, the stop top drivingly cooperating with the connecting structure; wherein, when the pressure-bearing cover is in the locked position, the stop top avoids the connecting structure, and when the pressure-bearing cover is in the unlocked position, the stop top abuts against the connecting structure to open the outlet of the sealing element.

[0006] The present invention utilizes a liner with mounting holes, and a pressure-bearing cover rotatably positioned below the liner, having a locked position and an unlocked position. A pressure-relief structure is connected to the pressure-bearing cover and extends through the mounting holes into the liner; the pressure-relief structure rotates synchronously with the pressure-bearing cover. The pressure-relief structure includes a valve body and a valve core structure. The valve body has a valve cavity and an inlet and an outlet communicating with the valve cavity. The valve core structure includes a connecting structure and a sealing element, with the sealing element corresponding to the outlet. A reset element engages with the connecting structure to keep the sealing element in the position blocking the outlet. A stop is positioned on the liner and engages with the connecting structure. When the pressure-bearing cover is in the locked position, the stop avoids the connecting structure. When the pressure-bearing cover is in the unlocked position, the stop engages with the connecting structure to open the outlet. With the above-described configuration, after cooking, the pressure-bearing lid moves from the locked position to the unlocked position. At this point, the top abuts against the connecting structure, opening the vent and maintaining this open position. This ensures continuous communication between the inside and outside of the lid assembly. When the lid is closed again, the pressure inside the pot is released through the vent, making it safer for the user. Therefore, the technical solution of this application effectively solves the problem in related technologies where the vent is blocked after the lid is opened, potentially leading to danger.

[0007] Furthermore, the cover is also provided with a clearance hole, which communicates with the mounting hole. The clearance hole is used to avoid the connection structure, and the abutment is provided on the wall of the clearance hole and protrudes towards the rotation axis of the pressure cover. The aforementioned clearance hole provides space for the installation of the pressure relief structure, and the abutment is provided on the wall of the clearance hole, which makes the installation of the abutment easier and more stable.

[0008] Furthermore, the top abutment is a ramp, and the distance between the ramp and the rotation axis of the pressure cover gradually decreases from the locked position to the unlocked position. The ramp has a simple structure, is easy to install, and can effectively drive the connecting structure.

[0009] Furthermore, the cover assembly also includes a drive component, which is mounted on the liner and can engage with the connecting structure to open the vent of the seal. When the pressure cover is in the locked position, the connecting structure and the drive component are aligned accordingly; when the pressure cover is in the unlocked position, the connecting structure and the drive component are misaligned. This configuration effectively ensures the smooth operation of the driving connecting structure.

[0010] Furthermore, the cover assembly also includes a steam seat, which is disposed within the mounting hole and connected to the pressure cover. The connection structure includes a connecting rod and a transmission component. The transmission component is movably mounted on the steam seat, and the connecting rod is movably inserted through the vent hole and correspondingly positioned with the transmission component. A portion of the transmission component extends out of the steam seat. This configuration allows for a more regular overall structure, and the steam seat effectively isolates the exterior and interior of the cover.

[0011] Furthermore, the transmission component includes a push rod portion and a pusher head. The push rod portion passes through the steam seat, and the pusher head is connected to the push rod portion and located on the outside of the steam seat. The pusher head can engage with the pusher head in a driving action. The transmission component is positioned between the connecting rod and the driving component, which results in a larger distance between the driving component and the vent. This ensures that when fluid is discharged from the vent, the fluid will not have a significant impact on the driving component, thereby guaranteeing the stability of the driving component's operation.

[0012] Furthermore, the transmission component also includes a guide portion, which is connected to the pusher top and spaced apart from the pusher rod portion. The cover assembly also includes a fixing seat with a guide hole. The fixing seat is mounted on the steam seat, and the guide portion passes through the guide hole. The guide portion is movably mounted in the guide hole, which makes the movement of the transmission component more stable and the direction of movement more fixed.

[0013] Furthermore, the transmission component also includes a first stop on the guide portion and a second stop on the steam seat. The first and second stops are engaged to prevent the steam seat and the transmission component from separating. The engagement of the first and second stops prevents the steam seat and the transmission component from separating; that is, when the reset component drives the connecting structure to move, the first and second stops are engaged.

[0014] Furthermore, there are multiple vents and multiple seals, with each seal and vent corresponding to a specific vent. This configuration improves venting efficiency and reduces the waiting time before opening the cover.

[0015] According to another aspect of this utility model, a cooking appliance is provided, including a lid assembly, which is the lid assembly described above. When the lid is opened, the connecting structure of the lid assembly can abut against the top, thereby opening the vent of the sealing element, thus making it safer for the user. Therefore, the cooking appliance with the lid assembly described above also has the aforementioned advantages. Attached Figure Description

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0034] like Figure 1 as well as Figures 3 to 7As shown, in this embodiment, the cover assembly includes: a liner 10, a pressure-bearing cover 20, a pressure-relief structure 30, a reset member 50, and a top abutment 60. The liner 10 is provided with a mounting hole 11. The pressure-bearing cover 20 is rotatably disposed below the liner 10 and has a locked position and an unlocked position. The pressure-relief structure 30 is connected to the pressure-bearing cover 20 and extends out of the liner 10 through the mounting hole 11. The pressure-relief structure 30 rotates synchronously with the pressure-bearing cover 20. The pressure-relief structure 30 includes a valve body 31 and a valve core structure 32. The valve body 31 has a valve cavity 311 and an air inlet 312 and an air outlet 313 communicating with the valve cavity 311. The valve core structure 32 includes a connecting structure 321 and a sealing member 322 disposed on the connecting structure 321. The sealing member 322 is correspondingly disposed with the air outlet 313. The reset member 50 is driven to cooperate with the connecting structure 321 to keep the sealing member 322 in the position of blocking the air outlet 313. The abutment 60 is disposed on the cover 10 and engages with the connecting structure 321. When the pressure cover 20 is in the locked position, the abutment 60 avoids the connecting structure 321; when the pressure cover 20 is in the unlocked position, the abutment 60 engages with the connecting structure 321 to open the vent 313 of the seal 322.

[0035] Applying the technical solution of this embodiment, the liner 10 is provided with a mounting hole 11, and the pressure-bearing cover 20 is rotatably disposed below the liner 10. The pressure-bearing cover 20 has a locked position and an unlocked position. The pressure relief structure 30 is connected to the pressure-bearing cover 20 and extends out of the liner 10 through the mounting hole 11. The pressure relief structure 30 rotates synchronously with the pressure-bearing cover 20. The pressure relief structure 30 includes a valve body 31 and a valve core structure 32. The valve body 31 has a valve cavity 311 and an air inlet 312 and an air outlet 313 communicating with the valve cavity 311. The valve core structure 32 includes a connecting structure 321 and a sealing element 322, and the sealing element 322 is correspondingly disposed with the air outlet 313. The reset element 50 is driven to cooperate with the connecting structure 321 so that the sealing element 322 can be held in the position of blocking the air outlet 313. The abutment 60 is disposed on the liner 10, and the abutment 60 is driven to cooperate with the connecting structure 321. When the pressure cap 20 is in the locked position, the abutment 60 avoids the connecting structure 321. When the pressure cap 20 is in the unlocked position, the abutment 60 abuts against the connecting structure 321 to open the vent 313 of the sealing element 322. Through the above arrangement, after cooking, the pressure cap 20 moves from the locked position to the unlocked position. At this time, the abutment 60 can abut against the connecting structure 321, thereby opening the vent 313 and maintaining it in the open position. This ensures that the inside and outside of the cap assembly are always connected. When the cap is closed again, the pressure inside the pot is released through the vent 313, making it safer for the user. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies where the vent is blocked after the cap is opened, which can easily lead to danger.

[0036] like Figures 3 to 6 As shown, in this embodiment, the cover 10 is also provided with a clearance hole 12, which communicates with the mounting hole 11. The clearance hole 12 is used to avoid the connecting structure 321. The abutment 60 is provided on the hole wall of the clearance hole 12 and protrudes towards the rotation axis of the pressure cover 20. The clearance hole 12 provides space for the installation of the pressure relief structure 30, and the abutment 60 is provided on the hole wall of the clearance hole 12, which makes the installation of the abutment 60 easier and more stable.

[0037] In an embodiment not shown in the figure, the abutment 60 is disposed on the cover 10, that is, the abutment 60 protrudes upward from the cover 10.

[0038] like Figure 6 As shown, in this embodiment, the abutment top 60 is an abutment slope 61. From the locked position to the unlocked position of the pressure cover 20, the distance between the abutment slope 61 and the rotation axis of the pressure cover 20 gradually decreases. The abutment slope 61 has a simple structure, is easy to install, and can effectively drive the connecting structure 321.

[0039] like Figure 3 and Figure 4 As shown, in this embodiment, the cover assembly further includes a driving member 40. The driving member 40 is disposed on the liner 10 and can drive and cooperate with the connecting structure 321 to open the vent 313 of the sealing member 322. When the pressure cover 20 is in the locked position, the connecting structure 321 and the driving member 40 are correspondingly arranged. When the pressure cover 20 is in the unlocked position, the connecting structure 321 and the driving member 40 are misaligned. The above arrangement can effectively ensure the driving connection structure 321.

[0040] It should be noted that the aforementioned drive component 40 includes either an electric or a manual operating component. Electric components include solenoid valves or electric actuators, etc. Manual operating components include manual knobs or manual push knobs, etc.

[0041] like Figure 1 , Figure 3 , Figure 4 as well as Figure 10 As shown, in this embodiment, the cover assembly further includes a steam seat 70, which is disposed within the mounting hole 11 and connected to the pressure cover 20. The connecting structure 321 includes a connecting rod 3211 and a transmission component 3212. The transmission component 3212 is movably disposed on the steam seat 70, and the connecting rod 3211 is movably inserted through the vent hole 313 and correspondingly disposed with the transmission component 3212. A portion of the transmission component 3212 extends out of the steam seat 70. The above arrangement makes the overall structure more regular, and the steam seat 70 can isolate the outside and inside of the cover 10.

[0042] like Figure 1 , Figure 2 , Figure 9 as well as Figure 11 As shown, in this embodiment, the transmission component 3212 includes a push rod portion 32121 and a push top portion 32122. The push rod portion 32121 passes through the steam seat 70, and the push top portion 32122 is connected to the push rod portion 32121 and located on the outside of the steam seat 70. The abutment portion 60 can drive and cooperate with the push top portion 32122. The transmission component 3212 is disposed between the connecting rod 3211 and the driving component 40, which makes the distance between the driving component 40 and the vent 313 larger. This way, when the fluid is discharged from the vent 313, the fluid will not have a significant impact on the driving component 40, thereby ensuring the stability of the driving component 40.

[0043] Specifically, the cross-sectional area of ​​the push rod portion 32121 is smaller than the cross-sectional area of ​​the push top 32122, which ensures that the drive component 40 drives the transmission component 3212, thereby reducing the need for high precision during assembly and thus lowering the difficulty of assembly.

[0044] like Figure 11 and Figure 12 As shown, in this embodiment, the transmission component 3212 further includes a guide portion 32123. The guide portion 32123 is connected to the push top 32122 and spaced apart from the push rod portion 32121. The cover assembly also includes a fixing seat 80, which has a guide hole 81. The fixing seat 80 is mounted on the steam seat 70, and the guide portion 32123 passes through the guide hole 81. The guide portion 32123 is movably disposed within the guide hole 81, which makes the movement of the transmission component 3212 more stable and the direction of movement relatively fixed.

[0045] Specifically, the guide hole 81 is a rectangular hole, and the guide portion 32123 is a guide plate. The guide plate passes through the rectangular hole, which improves the guiding effect, enabling limiting in four directions: up, down, left, and right. A portion of the guide hole 81 is located below the steam seat 70, and the lower surface of the steam seat 70 and the guide hole 81 jointly guide the guide portion 32123. The guide portion 32123 is sandwiched between the guide hole 81 and the lower surface of the steam seat 70, thus ensuring the guiding effect.

[0046] like Figure 1 , Figure 2 , Figure 11 as well as Figure 12As shown, in this embodiment, the transmission member 3212 further includes a first stop member 32124 disposed on the guide portion 32123, and a second stop member 71 disposed on the steam seat 70. The first stop member 32124 and the second stop member 71 can engage to prevent the steam seat 70 from separating from the transmission member 3212. The first stop member 32124 and the second stop member 71 can engage to prevent the steam seat 70 from separating from the transmission member 3212, that is, when the reset member 50 drives the connecting structure 321 to move, the first stop member 32124 and the second stop member 71 can engage to prevent separation.

[0047] Specifically, the bottom surface of the steam seat 70 is provided with a recess, and the second stop 71 is formed from the edge of the recess toward the drive member 40, which can effectively reduce the thickness of the cover assembly.

[0048] like Figure 8 and Figure 9 As shown, in this embodiment, there are multiple vent holes 313 and multiple sealing elements 322, with each sealing element 322 and vent hole 313 corresponding to the other. This arrangement improves exhaust efficiency and reduces the waiting time for opening the cover.

[0049] Specifically, in Embodiment 1, there are two vent holes 313 and two sealing elements 322. The two sealing elements 322 and the two vent holes 313 are arranged in a one-to-one correspondence. The two sealing elements 322 include an inner sealing element and an outer sealing element. The inner sealing element is disposed inside the valve cavity 311 and seals with the inner side of one vent hole 313. The outer sealing element is disposed outside the valve cavity 311 and seals with the outer side of the other vent hole 313. The area of ​​the vent hole 313 corresponding to the inner sealing element is the first area S1, and the area of ​​the vent hole 313 corresponding to the outer sealing element is the second area S2. The first area S1 and the second area S2 satisfy the condition: S1 > S2.

[0050] The fluid in the valve cavity 311 exerts force on both the inner and outer seals simultaneously. When the seal blocks the vent 313, the fluid can squeeze the inner seal, causing the outer seal to tend to move towards the inner seal, thus improving the sealing effect. Furthermore, since the first area S1 is larger than the second area S2, the force exerted by the fluid on the inner seal is greater than the force exerted by the fluid on the outer seal. As a result, under the force on the inner seal, the connecting rod 3211 can pull the outer seal, allowing the outer seal to fit against the valve body 31, further enhancing the sealing effect. Since both the inner and outer seals are mounted on the connecting rod 3211, and the inner and outer seals can move synchronously, when the seal 322 moves from blocking the vent 313 to opening the vent 313, the fluid can flow out from the gap between the outer seal and the corresponding vent 313. At the same time, there is also a gap between the inner seal and the corresponding vent 313, through which the fluid can flow out. When the seal continues to move, the resistance encountered by the seal 322 is small, meaning that the movement of the valve core structure 32 is relatively easy.

[0051] When all seals 322 open the vent 313, the distance between the inner seal and the corresponding vent 313 is a first distance A1, and the distance between the outer seal and the corresponding vent 313 is a second distance A2, wherein the first distance A1 and the second distance A2 satisfy: A1 < A2. With the above settings, when the valve body assembly switches from the open state to the closed state, the inner seal can first block the corresponding vent 313, and then the outer seal blocks the corresponding vent 313. When the outer seal blocks the corresponding vent 313, the inner seal can deform. When the valve body assembly switches from the closed state to the open state, the inner seal resets, thus making the movement of the sealing structure easier.

[0052] According to another aspect of this application, a cooking appliance is provided. The cooking appliance of this embodiment includes a lid assembly, which is the lid assembly described above. When the lid is opened, the connecting structure 321 can abut against the top 60, thereby allowing the sealing member 322 to open the vent 313, thus making it safer for the user. Therefore, the cooking appliance with the lid assembly described above also has the aforementioned advantages.

[0053] The cooking appliance in this embodiment includes an electric pressure cooker or a rice cooker.

[0054] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0055] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0056] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0057] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
