In the state of opening the cover, the lock catch is released between the pot cover teeth and the pot body teeth, and the pot cover can be safely opened.
Referring to fig. 3 and 4, the pot cover of the cooking appliance includes a lower cover 1, an upper cover 2, a valve opening stopping assembly 3 and an opening stopping assembly 4, the upper cover 2 covers the lower cover 1, and the valve opening stopping assembly 3 and the opening stopping assembly 4 are both disposed between the upper cover 2 and the lower cover 1. The opening stopping plate component 4 is used for keeping the cover and the pot body in a cover closing state, and when the cooking cavity is in a high-pressure environment, the opening stopping plate component 3 prevents the opening stopping plate component 4 from moving outwards so as to keep the cover closing state and avoid potential safety hazards. When the cooking cavity is in a normal pressure environment, the opening stop valve assembly 3 does not influence the movement of the opening stop plate assembly 4, and after the opening stop plate assembly 4 is moved away, the pot cover can smoothly rotate and move from a cover closing state to a cover opening state.
The lower cover 1 is provided with a top wall 11 and a side wall 12, the valve opening stopping assembly 3 comprises a valve opening stopping seat 31 and a valve opening stopping 32, and the valve opening stopping seat 31 is fixed on the upper side of the top wall 11 of the lower cover 1. The valve seat 31 is provided with a passage 311 passing vertically therethrough, and the valve 32 is connected to the bottom of the passage 311 in a floating manner. The bottom of the check valve 32 is located outside the check valve seat 31 and extends into the cooking cavity, and the check valve 32 floats between a higher position and a lower position under the influence of the gas pressure in the cooking cavity. The top wall 21 of the upper cover 2 is provided with an opening 22, and the top end of the channel 311 extends into the opening 22. There is no clearance between passageway 311 and upper cover 1 roof 11, and the high-temperature gas who dashes out by passageway 311 gets into trompil 22, then directly exports, has avoided high-temperature gas to get into between lower cover 1 and the upper cover 2 and causes the problem of pot cover gas leakage. In addition, since the passage 311 of the check valve seat 31 is designed to extend into the opening 22 of the top wall 21 of the upper lid 2, the length of the passage 311 is long, and the floating time of the check valve 32 can be shortened. As an embodiment of the present application, the top end of the passage 311 stopping the valve seat 31 is located at the lower side of the top surface of the upper cap 2 in consideration of the integrity of the appearance of the top surface of the upper cap 2, so that the passage 311 is not clearly visible from the outside.
The check valve seat 31 is provided with a peripheral wall 312 having a substantially cylindrical shape, and the peripheral wall 312 surrounds and forms the passage 311. The opening stop plate assembly 4 includes an opening stop plate 41 extending along the side wall 12 and the top wall 11 of the inner lid 1, and a top end 410 of the opening stop plate 41 is located on the upper side of the top wall 11 of the lower lid 1. The stop plate 41 is provided with a fitting hole 411, and the fitting hole 411 is fitted around the outer side of the peripheral wall 312 of the stop valve seat 31. Normally, the stop plate 41 can move outward.
As an embodiment of the application, the peripheral wall is a hollow cylindrical seal (not shown) that deforms when compressed and compresses the channel. For example, the peripheral wall is made of a silicone material, and is free of perforations to maintain the tightness of the passage. As the stop plate 41 moves outwardly, the edges of its mating hole 411 press against the peripheral wall causing it to deform inwardly and compress the passage. The peripheral wall provides both give-off and maintains the tightness of the passage during the outward movement of the stop plate 41.
In the above embodiment, the channel is directly deformed to give way to the stop plate 41, and as another embodiment of the present application, the peripheral wall 312 may be provided with a through notch 313 for giving way to the stop plate 41.
As the stop plate 41 moves outwardly, as shown in connection with fig. 7, the edge 412 of the mating hole 411 follows the outward movement, through the notch 313 and into the channel 311. Because of the provision of the notch 313, even if the peripheral wall 312 of the check valve seat 31 is raised, the normal movement of the check plate 41 in the normal state is not affected.
The normal condition described above refers to a normal pressure condition inside the cooking chamber, and the movement of the check plate 41 is not affected by the check valve assembly 3 due to the provision of the notch 313. As shown in fig. 6, when the pressure in the cooking cavity is high, the opening stop valve 32 moves up along the channel 311 and is stopped inside the notch 313, which is equivalent to blocking the notch 313, and prevents the edge 412 of the fitting hole 411 of the opening stop plate 41 from entering the channel 311, thereby playing the opening stop function of the opening stop valve 32.
As an embodiment of the present application, the channel 311 is cylindrical, and the channel 311 is provided with 1/4-1/2 of the length of the notch 313 occupying the perimeter thereof, so as to ensure that there is enough room for the notch 313 to allow the edge 412 of the fitting hole 411 of the opening plate 41 to normally move.
Referring to fig. 4 to 7, in order to avoid air leakage from the gap 313 of the channel 311, the opening stop valve assembly 3 further includes a sealing ring 33, and the sealing ring 33 is substantially annular and is sleeved outside the peripheral wall 312 of the opening stop valve seat 31 to seal the gap 313. When the opening stop plate 41 moves outward, the edge 412 of the fitting hole 411 pushes against the sealing ring 33, and drives the sealing ring 33 to enter the channel 311 together, so as to maintain the sealing performance at the gap 313 of the channel 311.
A convex hull 330 protruding outwards is arranged at the position, corresponding to the gap 313, of the sealing ring 33, and the convex hull 330 is arc-shaped and arranged along the circumferential direction of the sealing ring 33; the convex hull 330 may also be considered to be disposed along the outer perimeter of the gap 313 of the check valve seat 31. When the opening stop plate 41 moves outward, the edge 412 of the fitting hole 411 presses the convex hull 330, causing the convex hull 330 to deform; after the stop plate 41 is reset, the convex hull 330 is restored to the original state, and the pushing edge 412 leaves the sealing ring 3. The convex hull 330 provides the deformation of the sealing ring 3, so that the sealing ring 3 is prevented from being excessively deformed due to the pushing of the edge 412 after being used for multiple times, and the normal function is prevented from being influenced; in addition, when the opening stop plate 41 is reset, the edge 412 is pushed, so that the opening stop plate 41 is separated from the opening stop valve seat 31.
In one embodiment of the present invention, in order to ensure the sealing performance of the cooking cavity under high pressure environment, a valve stop seal 34 is sleeved on the end of the valve stop 32, the valve stop seal 34 is located outside the valve stop seat 31, and when the valve stop 32 is located at the higher position, the valve stop seal 34 seals between the valve stop 32 and the opening at the bottom of the passage 311, and the valve stop 32 is clamped to ensure that the valve stop 32 does not completely enter the passage 311.
The operation of the opening stop plate assembly 4 will be briefly described, and the opening stop plate assembly 4 includes the opening stop plate 41, the spring 42 and the boss 43. The bottom end 413 of the opening stopping plate 41 extends to the outer side of the side wall 12, and the convex column 43 is fixed to the bottom end 413, passes through the side wall 12 of the lower cover 1, protrudes into the right lower part of the top wall 11, and is clamped into the pot body (not shown), so that the pot cover is prevented from rotating relative to the pot body, and the opening stopping purpose is realized. The spring 42 is located between the opening stopping plate 41 and the side wall of the upper cover 2, and when the opening stopping plate 41 moves outwards, the spring 42 is compressed and drives the convex column 43 to move outwards to leave the pot body, so that the pot cover can rotate relative to the pot body. The driving of the stop plate 41 is not essential in this case and any suitable solution known in the art can be used, not described in detail here, without limitation.
