Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1 to 7, the cooking appliance of the present application includes: the device comprises a device body 10, a cover body 20, a pressure limiting valve 30 and a driving structure 40. The appliance body 10 has a cooking cavity 1; the cover body 20 is arranged on the appliance body 10 in a covering manner, the cover body 20 comprises a locking position locked on the appliance body 10 and a non-locking position unlocked on the appliance body 10, and an exhaust channel 2 communicated with the cooking cavity 1 is arranged on the cover body 20; the pressure limiting valve 30 is plugged at the air outlet of the air exhaust channel 2 when the cover body 20 is located at the locking position; the actuating structure 40 actuates the pressure limiting valve 30 away from the exhaust port with the cover 20 in the unlocked position.

By applying the technical scheme of the embodiment, when the cover body 20 is located at the non-locking position, the driving structure 40 can drive the pressure limiting valve 30 to be away from the exhaust port of the exhaust passage 2, at the moment, the cooking cavity 1 in the cooking appliance is communicated with the outside atmosphere through the exhaust passage 2, and even if the cooking appliance is in a heating state, hot air generated in the cooking cavity 1 can be exhausted from the exhaust passage 2, so that the phenomenon that the cooking appliance explodes a pot is avoided, and the safety of the cooking appliance is improved. When the cover 20 is rotated to the locking position, the driving structure 40 can be away from the pressure limiting valve 30, and at this time, the pressure limiting valve 30 blocks the exhaust channel 2, so that the cooking utensil can be normally pressed upwards. When the cover body 20 is located at the locking position, the cover teeth 232 on the cover body 20 and the pot teeth 11 on the appliance body 10 can be completely locked, and the tooth fastening amount between the cover teeth 232 and the pot teeth 11 is maximum, so that the pressure increase in the cooking appliance does not occur. The arrangement of the driving structure 40 can avoid the phenomenon of frying pan caused by the cover 20 not being locked with the appliance body 10, thereby improving the safety of the cooking appliance.

As shown in fig. 4 and 7, in the present embodiment, the driving structure 40 includes a lever 50 and a pushing structure 60, the lever 50 is pivotally disposed on the cover 20, a first end 51 of the lever 50 is located below the pressure limiting valve 30, the pushing structure 60 is disposed on the appliance body 10, when the cover 20 is located at the locking position, the pushing structure 60 is engaged with a second end 52 of the lever 50, a second end of the lever 50 is raised, the first end of the lever 50 sinks and is away from the pressure limiting valve 30, the pressure limiting valve is sealed at the air outlet, when the cover 20 is located at the non-locking position, the pushing structure 60 is dislocated with the second end 52 of the lever 50, and the lever 50 pushes the pressure limiting valve 30 away from the air outlet. In the above structure, when the cover is in the non-locking position, the first end 51 of the lever 50 can push up the pressure limiting valve 30, so that the cooking cavity 1 is communicated with the outside atmosphere, thereby ensuring that the inside of the cooking utensil cannot be pressed upwards when the cover 20 is in the non-locking position, and avoiding the danger of frying the pot in the cooking utensil. When the lid is located at the locking position, the pushing structure 60 pushes the second end 52 of the lever 50 upwards to make the first end 51 of the lever 50 far away from the pressure limiting valve 30, and at this time, the pressure limiting valve 30 can block the exhaust port of the exhaust channel 2, so that the cooking appliance can normally press upwards to meet the pressure cooking requirement of a user.

As shown in fig. 1, 2 and 7, in the present embodiment, the pushing structure 60 is a protrusion protruding upward. In the above configuration, when the cover rotates from the unlocked position to the locked position, the protrusion pushes the second end 52 of the lever 50 upward, so that the first end 51 of the lever 50 falls away from the pressure limiting valve 30. The pressure limiting valve 30 can block the exhaust port of the exhaust passage 2, and the cooking utensil can be normally pressed upwards. The structure is simple, a driving part is not needed, and the pressure limiting valve 30 can be jacked up and fallen back by opening and closing the cover, so that the production cost is reduced. In addition, the above structure facilitates the processing of the pushing structure 60.

In other embodiments not shown in the drawings, a first magnetic block may be disposed at the second end 52 of the lever 50, and the pushing structure 60 includes a second magnetic block, and a magnetic pole of the first magnetic block close to the second magnetic block is the same as a magnetic pole of the second magnetic block close to the first magnetic block. In the above structure, the first magnetic block can move upward under the action of the repulsive force of the second magnetic block, so as to drive the second end of the lever 50 to move upward, and the first end 51 of the lever 50 falls and is far away from the pressure limiting valve 30. The pressure limiting valve 30 can block the exhaust port of the exhaust passage 2, and the cooking utensil can be normally pressed upwards. The above structure can also achieve the pushing effect of the lever 50.

Directly pushing the lever 50 by the pushing structure 60 requires a long length of the lever 50 from the pivot axis to the second end 52 of the lever 50, and therefore the pushing structure 60 needs to push the second end 52 of the lever 50 upward by a long distance, so that the first end of the lever 50 can be smoothly separated from the pressure limiting valve 30. This way, the lever 50 requires a large movement space, which is not conducive to the compact design of the cover. To solve the above problem, as shown in fig. 4, 7, 10 to 12, in the present embodiment, the cover 20 is provided with a movable top pillar 70, the top pillar 70 is located below the second end 52 of the lever 50, and the protrusion drives the lever 50 to rotate through the top pillar 70. In the above structure, the pushing structure 60 drives the second end of the lever 50 to move upwards by pushing the top pillar 70, so that the length of the lever 50 from the pivot axis to the second end 52 of the lever 50 is reduced, the movement space required by the lever 50 is reduced, and the miniaturization design of the cooking appliance is facilitated.

As shown in fig. 5, 8 to 12, in the present embodiment, the lower surface of the top pillar 70 includes a slope surface in abutting engagement with the protrusion, and the slope surface gradually inclines upward in the locking direction n of the cover body 20. In the above structure, when the cover 20 rotates toward the locking direction n, the pushing structure 60 will abut against the inclined surface of the top pillar 70, and the top pillar 70 will move upward under the action of the inclined surface, so that the second end of the pushing lever 50 moves upward. The structure enables the cover body 20 to smoothly transit in the process of rotating to the locking position by arranging the inclined surface, so that the use experience of a user is improved.

It should be noted that in other embodiments not shown in the drawings, the upper surface of the protrusion may be a slope adapted to (at the same angle as) the slope of the top pillar. The structure can also achieve the purpose of smooth transition of the cover body in the process of rotating to the locking position. In addition, in another embodiment not shown in the drawings, both the lower surface of the top pillar in abutting engagement with the protrusion and the upper surface of the protrusion in engagement with the top pillar may be inclined surfaces. The structure enables the cover body to be more smooth when locked, and improves the use experience of users. As shown in fig. 4 and 7, in the present embodiment, the cover 20 is provided with a fixing seat 80, and the top pillar 70 is movably inserted into the fixing seat 80. In the above structure, the top pillar 70 has a floating position and a sinking position. When the cover 20 is in the unlocked position, the top post is in the lowered position, which raises the first end 51 of the lever 50 upward, thereby actuating the pressure limiting valve 30 to be raised. When the lid 20 is located at the locking position, the pushing structure 60 pushes the top pillar 70 to be located at the floating position, and the top pillar 70 drives the first end 51 of the lever 50 to be away from the pressure limiting valve 30, so that the pressure limiting valve 30 blocks the exhaust passage 2, and the cooking utensil can be normally pressed upwards. The above structure can play a role of fixing the ejection column 70 by arranging the fixing seat 80, thereby facilitating the ejection column 70 to eject the lever 50.

It should be noted that, as shown in fig. 11 and 12, the top pillar 70 includes a fitting portion 71 and an upper pushing portion 72 disposed on the fitting portion 71, a lower surface of the fitting portion 71 forms an inclined surface, and the pushing portion 72 directly contacts with the lever 50 to push the lever 50. The matching portion 71 is provided with a buckle 711 extending upwards, the fixing seat 80 is provided with a bayonet 82, the top pillar 70 is clamped in the bayonet 82 of the fixing seat 80 through the buckle 711, and the buckle 711 can move in the bayonet 82, so that the top pillar 70 can float in the fixing seat 80.

As shown in fig. 1 and fig. 8 to fig. 10, in the present embodiment, the cover 20 includes a cover body 24 and a connecting arm 90 disposed on the cover body 24, a mounting notch 21 is disposed at a position of a bottom edge of the cover body 24 corresponding to the connecting arm 90, and the fixing seat 80 is disposed at the mounting notch 21 and extends into the connecting arm 90. In the above structure, the fixing seat 80 extends outwards from the mounting notch 21, i.e. is horizontally mounted. The above structure makes full use of the space of the cover body 20 in the radial direction, thereby reducing the thickness of the cover body and realizing the miniaturization design of the cooking appliance.

As shown in fig. 8 to 10, in the present embodiment, the fixing base 80 includes a bottom wall 81, a portion of the top pillar 70 below the bottom wall 81 is engaged with the protrusion, the bottom of the connecting arm 90 is provided with a first avoidance concave portion 91, the first avoidance concave portion 91 is located at the front side of the top pillar 70 in the locking direction n of the cover body 20, and the upper surface of the first avoidance concave portion 91 is flush with the lower surface of the bottom wall 81 of the fixing base 80. In the above structure, when the cover body 20 rotates toward the locking direction n, the first avoiding concave portion 91 can avoid the pushing structure 60, and as the cover body 20 continues to rotate, the pushing structure 60 can abut against the inclined surface of the top pillar 70, so as to push the top pillar 70 upward. The upper surface of the first avoidance concave part 91 is flush with the lower surface of the bottom wall 81 of the fixed seat 80, so that the step surface can be reduced, and cleaning is facilitated.

It should be noted that the fixing seat 80 further includes a limiting plate 83, the limiting plate 83 is located at the rear side of the top pillar 70 in the locking direction n of the cover body 20, when the cover body 20 rotates to the locking position, if the cover body 20 continues to rotate in the locking direction n, the pushing structure 60 on the appliance body 10 will form a stop for the limiting plate 83, so that the user cannot continue to rotate the cover body 20 in the locking direction n, thereby prompting the user that the cover body 20 has rotated to the locking position.

As shown in fig. 4, 7, 11 and 12, in the present embodiment, a first elastic structure 100 is disposed between the cover 20 and the upper surface of the second end 52 of the lever 50, and the lever 50 drives the pressure limiting valve 30 away from the exhaust port under the elastic force of the first elastic structure 100; in the above structure, the cover 20 is provided with the guide post 221, the first elastic structure 100 is a spring, the spring is sleeved outside the guide post 221 in the circumferential direction, and the guide post 221 can move the spring in the vertical direction. The first elastic structure 100 is located between the cover 20 and the second end 52 of the lever 50, and the first elastic structure 100 pushes the second end 52 of the lever 50 downward by virtue of its own elastic restoring force, so that the first end 51 of the lever 50 maintains the pushed state of the pressure limiting valve 30. When the lid 20 is located at the locking position, the pushing structure 60 drives the pushing post 70 to push the second end 52 of the lever 50 upward, and at this time, the pushing force of the pushing structure 60 is greater than the elastic restoring force generated by the first elastic structure 100, so that the second end 52 of the lever 50 moves upward, the first end 51 of the lever 50 is driven to be away from the pressure limiting valve 30, the pressure limiting valve 30 can fall down by the self-gravity to block the exhaust port of the exhaust channel 2, and the cooking utensil can be normally pressed upward. When the cover 20 is in the non-locking position, the lever 50 can maintain the pushing state of the pressure limiting valve 30. In addition, when the cover 20 moves from the locked position to the unlocked position, the first elastic structure 100 can also enable the top pillar 70 to automatically return to the sinking position, thereby facilitating the user experience. Of course, in other embodiments not shown in the drawings, a first magnetic structure may be disposed between the cover 20 and the upper surface of the second end 52 of the lever 50, and the first magnetic structure makes the cover and the second end 52 of the lever 50 move away from each other by means of a repulsive force, so that the first end 51 of the lever 50 maintains a pushing state of the pressure limiting valve 30. In other embodiments not shown in the drawings, a second elastic structure or a second magnetic structure may be disposed between the cover 20 and the lower surface of the first end 51 of the lever 50, and the lever 50 drives the pressure limiting valve 30 away from the exhaust port under the elastic force of the second elastic structure or the repulsive force of the second magnetic structure. The above structure also has an effect of maintaining the lever 50 in the pushed state against the pressure limit valve 30.

In other embodiments, which are not shown in the figures, it is also possible to make the moment of gravity of the second end 52 of the lever 50 greater than the sum of the moment of gravity of the first end 51 of the lever 50 and the moment of force generated by the pressure-limiting valve 30 at the first end 51 of the lever 50. The above structure can maintain the lever 50 in the pushed state of the pressure limit valve 30 by the self-weight of the second end 52 of the lever 50. The structure is simple, and the production and the processing are convenient.

As shown in fig. 1 and 3, in the present embodiment, the cover body 20 is detachably provided on the device body 10, the cover body 20 includes a surface cover 22 and an inner cover 23 provided in the surface cover 22, and the inner cover 23 is provided with a second escape recess 231 for escaping the lever 50. In the above structure, since the lever 50 can rotate between the face cover 22 and the inner cover 23, providing the second escape recess 231 extending downward on the inner cover 23 can increase the movement space of the lever 50, so that the movement of the lever 50 is not interfered.
