Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1-2 and 5-6, an embodiment of the present invention provides a cooking apparatus 200, which includes a pot body 210, an inner pot 220 sleeved in the pot body 210, and a cover 100.
The cover body 100 comprises an upper cover 10 and a heat-insulating cover plate 20 detachably arranged on the upper cover 10, and the upper cover 10 and the pot body 210 can be opened and closed to open or close the pot body 210. When the upper cover 10 is closed, the heat-insulating cover plate 20 can be covered on the inner pot 220 and form a cooking space with the inner pot 220, so as to process food materials by using the cooking space. The cover body 100 further comprises a driving assembly 30 and a clamping mechanism 70 both disposed on the upper cover 10, and the clamping mechanism 70 is switched between a cover position for clamping the inner pot 220 and the heat-insulating cover plate 20 and a cover opening position for allowing the heat-insulating cover plate 20 to be separated from the inner pot 220 under the action of the driving assembly 30. When the cooking utensil 200 works, the pressure in the cooking space rises, the air pressure borne by the heat-insulating cover plate 20 is large, the heat-insulating cover plate 20 and the inner pot 220 are locked by the clamping mechanism 70, and the cover body 100 is prevented from being opened abnormally under the action of high pressure.
The clamping mechanism 70 comprises a first clamping jaw 72 and a second clamping jaw 74 which move towards the direction of approaching to and departing from each other, the first clamping jaw 72 and the second clamping jaw 74 move towards the direction of approaching to each other and both clamp the heat-insulating cover plate 20 and the inner pot 220, or the first clamping jaw 72 and the second clamping jaw 74 move towards the direction of departing from each other and both separate from the heat-insulating cover plate 20 and the inner pot 220. The first jaw 72 and the second jaw 74 are oppositely arranged on the upper cover 10, when the first jaw 72 and the second jaw 74 move towards the direction of mutual approaching, the first jaw 72 and the second jaw 74 respectively approach the edge of the heat-insulating cover plate 20 and the inner pot 220, and the heat-insulating cover plate 20 and the inner pot 220 can be clamped; when the first jaw 72 and the second jaw 74 move in a direction away from each other, the first jaw 72 and the second jaw 74 move away from the insulating cover plate 20 and the edge of the inner pot 220, respectively, allowing the insulating cover plate 20 to be separated from the inner pot 220.
As shown in fig. 3-4, the driving assembly 30 includes a driving member 32, a driving member 34 and a linkage member 36, the driving member 34 is disposed between the driving member 32 and the linkage member 36, and the first jaw 72 and the second jaw 74 are drivingly connected to the driving member 34 and the linkage member 36, respectively; the driving member 32 is driven by the driving member 34 to reciprocate, and the link member 36 is driven to reciprocate in a direction opposite to the moving direction of the driving member 34. When the driving member 32 drives the transmission member 34 to move in the first direction, the moving transmission member 34 can simultaneously drive the link member 36 to move in the direction opposite to the moving direction of the transmission member 34.
For example, in the view shown in FIG. 4, when the transmission member 34 moves to the left, the linkage member 36 is moved to the right; meanwhile, when the first jaw 72 is driven by the transmission member 34 to move leftwards, the second jaw 74 is driven by the linkage member 36 to move rightwards, and both move away from each other and are separated from the inner pot 220 and the heat-insulating cover plate 20. When the transmission piece 34 moves rightwards, the linkage piece 36 is driven to move leftwards; meanwhile, when the first jaw 72 is driven by the transmission member 34 to move rightwards, the second jaw 74 is driven by the linkage member 36 to move leftwards, and both move towards the direction of approaching each other, and both clamp the inner pot 220 and the heat preservation cover plate 20.
The driving assembly 30 further includes a linkage gear 37, the transmission member 34 and the linkage member 36 are stacked, the linkage gear 37 is disposed between the transmission member 34 and the linkage member 36, and two surfaces of the transmission member 34 and the linkage member 36 facing each other are respectively provided with a first rack and a second rack engaged with the linkage gear 37 for transmission, which is equivalent to that the first rack is engaged with one side of the linkage gear 37 for transmission, and the second rack is engaged with the other side of the linkage gear 37 for transmission relative to the first rack 343. And the extending directions of the first rack and the second rack are the same. When the transmission member 34 moves away from the second jaw 74, the first rack 343 also moves away from the second jaw 74, and drives the linking gear 37 to rotate, so as to drive the second rack and the linking member 36 to move in a direction opposite to the moving direction of the transmission member 34 through the linking gear 37, that is, drive the linking member 36 to move away from the first jaw 72, and thus drive the first jaw 72 and the second jaw 74 to move away from each other. Similarly, when the driving member 34 moves in the first direction to approach the second jaw 74, the driving gear 37 drives the link member 36 to move in the direction to approach the first jaw 72, so as to drive the first jaw 72 and the second jaw 74 to approach each other.
In some embodiments, the transmission member 34 is provided with a driving rack extending along the first direction, and the output end of the driving member 32 is provided with a driving gear meshed with the driving rack. When the output end of the driving member 32 drives the driving gear to rotate, the driving rack engaged with the driving gear slides along the extending direction of the driving rack, thereby driving the transmission member 34 to reciprocate.
In some embodiments, the cover body 100 further includes a detection component disposed on the upper cover 10, the detection component is used for detecting whether the clamping mechanism 70 is located at the cover closing position and the cover opening position, and the driving component 30 is controlled to stop working when the clamping mechanism 70 is located at the cover closing position and the cover opening position. That is to say, after the clamping mechanism 70 is in place for closing the cover or is in place for opening the cover, the driving assembly 30 stops working and no longer drives the clamping mechanism 70 to move, so as to prevent the clamping mechanism 70 from being damaged due to the fact that the driving assembly 30 forcibly drives the clamping mechanism 70 to move when no moving space exists. Meanwhile, the detection assembly can detect whether the box cover of the clamping mechanism 70 is in place or not, and can perform pressurization work after the box cover is in place, so that the danger of explosion and the like caused by pressurization when the box cover is not in place is prevented; the detection assembly can also detect whether the clamping mechanism 70 is opened in place or not, so that the situation that the cooking appliance cannot be opened due to the fact that the clamping mechanism 70 is not opened in place is avoided.
As shown in fig. 5-8, in some embodiments, the detection assembly includes a first microswitch 82 and a second microswitch 84, the first microswitch 82 being located in the path of movement of the first jaw 72 and the second microswitch 84 being located in the path of movement of the second jaw 74; with the clamping mechanism 70 in the closed position, one of the first and second microswitches 82, 84 is triggered; when the clamping mechanism 70 is located at the uncovering position, the other one of the first micro switch 82 and the second micro switch 84 is triggered, when the first micro switch 82 or the second micro switch 84 is triggered, the controller stops supplying power to the driving part, the driving part stops rotating, the uncovering or covering action of the clamping mechanism 70 is completed, the clamping mechanism 70 does not act, the clamping mechanism 70 is prevented from moving excessively, and the uncovering and covering accuracy is guaranteed.
In a specific embodiment, the first jaw 72 and the second jaw 74 are respectively provided with a first groove 71 and a second groove 73, when the clamping mechanism 70 is in the cover closing position, the trigger end of the first microswitch 82 is located in the first groove 71, the trigger end of the second microswitch 84 is located outside the second groove 73 and is triggered by being squeezed, the controller receives a trigger signal sent by the second microswitch 84, judges that the clamping mechanism 70 is in the cover closing position, and controls the driving assembly 30 to stop working; when the clamping mechanism 70 is in the uncovering position, the trigger end of the first microswitch 82 is positioned outside the first groove 71 and is extruded and triggered, the trigger end of the second microswitch 84 is positioned in the second groove 73, and the controller receives a trigger signal sent by the first microswitch 82, judges that the clamping mechanism 70 is in the uncovering position and controls the driving assembly 30 to stop working.
That is, when the controller receives the trigger signal sent by the first microswitch 82, it indicates that the clamping mechanism 70 is in the lid opening position, and when the controller receives the trigger signal sent by the second microswitch 84, it indicates that the clamping mechanism 70 is in the lid covering position, so that the controller can determine whether the clamping mechanism 70 is moved in place, and further, the situation that the clamping mechanism 70 is not moved in place or is moved excessively can be avoided.
It is understood that in other embodiments, the first jaw 72 and the second jaw 74 are respectively provided with a first rib (not shown) and a second rib (not shown); when the clamping mechanism 70 is in the cover closing position, the trigger end of the first microswitch 82 is abutted against the first convex strip, and the trigger end of the second microswitch 84 is disengaged from the second convex strip and is triggered after being extended; when the gripping mechanism 70 is in the open-lid position, the trigger end of the first microswitch 82 is disengaged from the first rib and is triggered after being extended, and the trigger end of the second microswitch 84 abuts against the second rib. That is, when the trigger terminals of the first and second micro switches 82 and 84 are compressed, no trigger signal is generated, and when the trigger terminals of the first and second micro switches 82 and 84 are released and extended, a trigger signal is generated, and after the controller receives the trigger signal, it can determine that the clamping mechanism 70 is in the open-cover position or the close-cover position.

Further, the first clamping jaw 72 or the second clamping jaw 74 is provided with a first matching part and a second matching part; when the clamping mechanism 70 is switched to the cover closing position, the trigger end of the third microswitch 86 corresponds to the first matching part and is triggered; when the clamping mechanism 70 is switched to the uncovering position, the trigger end of the third microswitch 86 corresponds to the second matching part and is triggered. When the trigger end of the third microswitch 86 is triggered, indicating that the clamping mechanism 70 is switched to the cover closing position or the cover opening position, no further movement is required, and the controller controls the driving assembly 30 to stop working.
