Detailed Description
It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The application will be described in detail below with reference to the drawings in connection with embodiments.
As shown in fig. 1 to 7, an electric pressure cooker of a first embodiment includes: the cooker body 10, the cooker cover 20, the pressure limiting valve 30, the rotating portion 40 and the pushing portion 50. Wherein, the pan body 10 is used for containing food to be cooked, and the pan body 10 is provided with pan teeth. The pot cover 20 is covered on the pot body 10, the pot cover 20 comprises a lock cover 21 and a lining 22 arranged on the lock cover 21, and the lock cover 21 is provided with cover teeth matched with the pot teeth. The pressure limiting valve 30 is arranged on the pot cover 20, when the pressure in the pot body 10 reaches a preset pressure value, the pressure limiting valve 30 is communicated with the gas in the pot body 10 and the external atmosphere, and when the pressure in the pot body 10 does not reach the preset pressure value, the pressure limiting valve 30 isolates the gas in the pot body 10 from the external atmosphere. The rotating part 40 is pivotally arranged on the liner 22 and connected with the lock cover 21, the lock cover 21 is driven by the rotating part 40 to rotate, the rotating part 40 is provided with a locking position, an unlocking position and an intermediate position between the locking position and the unlocking position, when the rotating part 40 rotates to the unlocking position, the pot teeth are separated from the cover teeth, when the rotating part 40 is positioned at the locking position, the pot teeth are matched with the cover teeth, and when the rotating part 40 rotates to the intermediate position, the pot teeth are in interference fit with the cover teeth. The push top 50 is pivotally arranged on the liner 22, the push top 50 is driven by the rotating part 40, when the rotating part 40 is located at the unlocking position, and in the process of rotating the rotating part 40 from the unlocking position to the middle position, the push top 50 is in propping fit with the pressure limiting valve 30 so as to enable gas in the pot body 10 to be communicated with the outside atmosphere, when the rotating part 40 rotates from the middle position to the locking position, the push top 50 is far away from the pressure limiting valve 30, and when the rotating part 40 rotates to the locking position, the push top 50 does not apply force to the pressure limiting valve 30 any more.
According to the first embodiment, the electric pressure cooker comprises a push-top 50 pivotally arranged on the liner 22, the push-top 50 is driven by the rotating part 40, when the rotating part 40 is located at the unlocking position, and in the process of rotating the rotating part 40 from the unlocking position to the intermediate position, the push-top 50 is in abutting fit with the pressure limiting valve 30 so as to enable air in the cooker body 10 to be communicated with the outside atmosphere, when the rotating part 40 rotates from the intermediate position to the locking position, the push-top 50 is far away from the pressure limiting valve 30, and when the rotating part 40 rotates to the locking position, the push-top 50 does not apply force to the pressure limiting valve 30. In the above structure, since the rotating portion 40 is rotated from the unlocking position to the intermediate position, the pushing portion 50 always pushes the pressure limiting valve 30, so that hot air in the pot can be discharged to the outside as much as possible, thereby reducing the pressure in the pot, further reducing the friction force generated between the pot teeth and the cover teeth when closing the cover, or avoiding the friction generated between the pot teeth and the cover teeth, improving the smoothness of opening and closing the pot cover 20, improving the user experience, and solving the problem of poor user experience of the electric pressure cooker in the prior art. In addition, when the rotating portion 40 rotates to the locking position, the pushing portion 50 does not apply an external force to the pressure limiting valve 30, so that the pressure limiting valve 30 can work normally in the cooking stage, and the purpose of high-pressure cooking is achieved.
The above-mentioned unlocking position refers to a position when the teeth are separated from the lid teeth, that is, a position when the teeth are completely displaced from the lid teeth in the radial direction of the pot body, and the pot cover 20 can be separated from the pot body 10. The above-mentioned locking position refers to a position when the pot teeth are engaged with the cover teeth, and the pot cover 20 cannot be separated from the pot body 10 at this time. The above-mentioned intermediate position refers to a position when the pan teeth are not completely separated from the lid teeth, that is, a position when the pan teeth and the lid teeth are offset from each other in the radial direction of the pan body, and at this time, the pan cover 20 cannot be separated from the pan body 10.
It should be noted that the pressure limiting valve 30 is separated from the ejector 50 during high-pressure cooking. When the pressure in the pot 10 reaches the preset pressure, a trigger signal is sent out, and the valve rod 61 of the electromagnetic valve pushes the pressure limiting valve 30 to enable the pressure limiting valve 30 to be communicated with the air in the pot 10 and the outside atmosphere. Of course, it should be understood by those skilled in the art that the structure of the push-up pressure limiting valve 30 is not limited to the valve stem 61 of the above-described solenoid valve, as long as the pressure limiting valve 30 can be pushed up to a predetermined position.
As shown in fig. 1 to 7, in the first embodiment, the driving post 41 is provided on the rotating portion 40, and the guiding hole 51 that mates with the driving post 41 is provided on the push top portion 50, and the guiding hole 51 includes a first guiding section 511 and a second guiding section 512. As shown in fig. 5, when the rotating portion 40 is located between the unlock position and the intermediate position, the driving post 41 is located in the first guide section 511, and when the rotating portion 40 is located at the intermediate position, the driving post 41 is located at the junction of the first guide section 511 and the second guide section 512. As shown in fig. 7, when the rotating portion 40 is located between the lock position and the intermediate position, the driving post 41 is located in the second guide section 512, wherein the push top portion 50 is in a stationary state when the driving post 41 slides in the guide direction of the second guide section 512 in the first guide section 511, the push top portion 50 moves away from the pressure limiting valve 30 when the driving post 41 slides from one end of the second guide section 512 near the first guide section 511 to the other end of the second guide section 512, the push top portion 50 is in a stationary state when the driving post 41 slides in the direction of the first guide section 511 in the second guide section 512, and the push top portion 50 moves toward the pressure limiting valve 30 when the driving post 41 slides from one end of the first guide section 511 near the second guide section 512 to the other end of the first guide section 511. The structure is simple and easy to realize.
As shown in fig. 5 and 7, in the first embodiment, when the driving column 41 is located in the first guide section 511, the hole wall of the first guide section 511 engaged with the driving column 41 coincides with the movement locus of the driving column 41, and the hole wall of the second guide section 512 engaged with the driving column 41 interferes with the movement locus of the driving column 41. When the driving column 41 is located in the second guiding section 512, the hole wall of the second guiding section 512 matched with the driving column 41 coincides with the moving track of the driving column 41, and the hole wall of the first guiding section 511 matched with the driving column 41 interferes with the moving track of the driving column 41. The structure is simple and easy to realize.
Specifically, as shown in fig. 5 and 7, when the driving post 41 is located in the first guide section 511, the hole wall of the first guide section 511 mated with the driving post 41 coincides with the movement track of the driving post 41, and since the hole wall of the second guide section 512 mated with the driving post 41 interferes with the movement track of the driving post 41, when the driving post 41 moves from the intermediate position to the locking position, the outer side wall of the driving post 41 applies an external force to the hole wall of the second guide section 512 mated therewith, pushing the pushing portion 50, so that the pushing portion 50 moves away from the pressure limiting valve 30. Similarly, when the driving post 41 is located in the second guiding section 512, the hole wall of the second guiding section 512 matched with the driving post 41 coincides with the movement track of the driving post 41, and because the hole wall of the first guiding section 511 matched with the driving post 41 interferes with the movement track of the driving post 41, when the driving post 41 moves from the middle position to the unlocking position, the outer side wall of the driving post 41 applies an external force to the hole wall of the first guiding section 511 matched with the driving post 41 to push the push top 50, so that the push top 50 moves towards the direction approaching the pressure limiting valve 30.
As shown in fig. 2 to 4 and 6, in the first embodiment, the electric pressure cooker further includes a solenoid valve 60. A solenoid valve 60 is provided on the liner 22, the solenoid valve 60 including a valve stem 61, and the push top 50 pushes the pressure limiting valve 30 through the valve stem 61. Specifically, when the rotating portion 40 is located at the unlocking position, and the rotating portion 40 rotates from the unlocking position to the intermediate position, the pushing portion 50 pushes the valve rod 61 of the electromagnetic valve 60, and the end portion of the valve rod 61 pushes the pressure limiting valve 30, so that the pressure limiting valve 30 is far away from the exhaust pipe, and the purpose of reducing the pressure in the pot body is achieved by communicating the gas in the pot body 10 with the outside air in the closing process. When the rotating portion 40 rotates from the neutral position to the locking position, the push top 50 is away from the valve stem 61, and the valve stem 61 is away from the pressure limiting valve 30 by the restoring force. The pressure limiting valve 30 is returned to the position for blocking the exhaust passage of the exhaust pipe under the action of gravity due to the loss of the butting of the external force, so that the purpose that the pressure limiting valve 30 can work normally in the cooking stage is achieved.
As shown in fig. 2 to 4 and 6, in the first embodiment, the valve rod 61 is sheathed with a spring.
As shown in fig. 5 and 7, in the first embodiment, the second guide section 512 includes a mating hole section 5121 and a dodge hole section 5122, and the dodge hole section 5122 is located inside the movement track of the drive column 41 when the rotating portion 40 is located between the unlock position and the intermediate position. Specifically, when the drive post 41 is positioned in the first guide section 511, the push top 50 abuts against the valve stem 61, and the spring on the valve stem 61 compresses, storing a certain elastic potential energy. When the driving post 41 starts to enter the second guiding section 512, the avoiding hole section 5122 is located at the inner side of the moving track of the driving post 41, so that the pushing top 50 rotates away from the pressure limiting valve 30 under the elastic restoring force of the spring, and the driving post 41 enters the avoiding hole section 5122 of the pushing top 50. The driving column 41 entering the avoidance hole section 5122 is kept in the avoidance hole section 5122 under the limit of the hole wall of the avoidance hole section 5122. The structure is simple, the cover closing is smooth, and the user experience is improved.
Of course, it will be appreciated by those skilled in the art that rotation of the push top 50 away from the pressure limiting valve 30 does not necessarily rely on the force of a spring that is fitted over the valve stem 61, but it is also possible to provide a torsion spring on the pivot axis of the push top 50 that stores potential energy when the rotary portion 40 is in the unlocked position, or between the unlocked position and the intermediate position. When the rotating portion 40 moves from the neutral position to the lock position, the push top portion 50 moves away from the pressure limiting valve 30 by the torsion spring. When the rotating portion 40 is in the locked position, the torsion spring is in a free state.
As shown in fig. 5 and 7, in the first embodiment, the width of the first guide section 511 and the width of the fitting hole section 5121 of the second guide section 512 are both equal to the diameter of the driving post 41. The structure has a guiding function, so that the cover can be further closed smoothly, and the user experience is improved. Of course, those skilled in the art will appreciate that the driving post 41 is in clearance fit with the inner wall of the first guide section 511 and the inner wall of the second guide section 512, so that the driving post 41 can slide smoothly in the first guide section 511 and the second guide section 512.
As shown in fig. 5, in the first embodiment, when the rotating portion 40 rotates to the unlock position, the line connecting the rotation center a of the driving post 41 and the axis of the driving post 41 is the first line a 1, and when the rotating portion 40 rotates to the intermediate position, the line connecting the rotation center a and the axis of the driving post 41 is the second line a 2, and the angle between the first line a 1 and the second line a 2 is between 10 ° and 35 °. The structure enables the distance between the unlocking position and the middle position to be long enough, namely the time for pushing the pressure limiting valve 30 when closing the cover is long enough, so the structure further enables hot air in the pot to be discharged to the outside as much as possible, pressure in the pot is reduced, and smoothness of opening and closing of the pot cover is improved.
As shown in fig. 2 and 3, in the first embodiment, the liner 22 is provided with a liner shaft 221, and the ejector 50 is a push rod, and the push rod is provided with a mounting hole 52 that mates with the liner shaft 221, and the push rod is pivotally provided on the liner 22 via the liner shaft 221.

The electric pressure cooker has the advantages that the structure is simple, the space can be fully utilized, and the structure of the electric pressure cooker is more compact.
As shown in fig. 8 to 10, the electric pressure cooker of the second embodiment is different from that of the first embodiment in the specific shape of the guide hole 51. Specifically, in the second embodiment, the guide hole 51 includes the first guide section 511, the second guide section 512, and the intermediate transition section 513 provided between the first guide section 511 and the second guide section 512. Wherein the first guiding section 511 and the second guiding section 512 are symmetrically arranged with respect to the intermediate transition section 513.
Preferably, in the second embodiment, the first guide section 511 and the second guide section 512 have the same length.
As shown in fig. 9 and 10, in the second embodiment, when the rotating portion 40 rotates to the intermediate position, the line connecting the rotation center a of the driving post 41 and the axis of the driving post 41 is the second line a 2, and when the rotating portion 40 rotates to the locking position, the line connecting the rotation center a and the driving post 41 is the third line a 3, and the angle between the second line a 2 and the third line a 3 is between 5 ° and 35 °.
