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 13, the cooking appliance of the first embodiment includes a pot body, a pot cover 10, a lid opening member 20, a lid opening confirmation key 30, and a heating device. The cooker body is provided with a cooking cavity, the cooker cover 10 is arranged on the cooker body in an openable and closable manner, the cover opening piece 20 can drive the cooker cover 10 to move from a closed position to an open position, if the cover opening confirmation key 30 receives a first trigger signal for confirming the cover opening, the cover opening piece 20 can drive the cooker cover 10 to move from the closed position to the open position, and if the cover opening confirmation key 30 does not receive the first trigger signal, the cover opening piece 20 cannot drive the cooker cover 10 to move from the closed position to the open position. The heating device is used for heating food in the cooking cavity
According to the technical scheme of the first embodiment, the cooking appliance is provided with the cover opening confirmation key 30, the cover opening member 20 can drive the pot cover 10 to move from the closed position to the open position, and if the cover opening confirmation key 30 does not receive the first trigger signal, the cover opening member 20 cannot drive the pot cover 10 to move from the closed position to the open position. The above structure makes a user need to perform a step of confirming whether to open the cover before opening the cover by the cover opening member 20, prevents the user from being scalded due to incorrect opening of the cover, and solves the problem of poor safety of the electric pressure cooker in the prior art.
In the first embodiment, the cooking appliance is an electric pressure cooker, the cover 10 is provided with cover teeth, the cooker body is provided with cooker teeth, when the cover teeth are matched with the cooker teeth, the cooker cover 10 is in a closed position, and when the cover teeth are separated from the cooker teeth, the cooker cover 10 is in an open position. Of course, the form of engagement of the pot body with the pot cover is not limited to the teeth and the teeth, and in other embodiments, the pot cover 10 may be provided with a first clasp, the pot body may be provided with a second clasp, the pot cover 10 is in the closed position when the first clasp is engaged with the second clasp, and the pot cover 10 is in the open position when the first clasp is separated from the second clasp.
In the first embodiment, a control board (not shown) is disposed in the pot body or the pot cover 10, if the cover opening confirmation key 30 receives the first trigger signal, the cover opening confirmation key 30 can send the second trigger signal to the control board, and if the control board receives the second trigger signal, the cover opening member 20 can drive the pot cover 10 to move from the closed position to the open position. The structure is controlled by the control panel, so that the structure is simple, the reflecting speed is high, and the operation of a user is convenient. In other embodiments, a purely mechanical structure, such as a lid opening confirmation key, may be movably disposed on the lid, such that when the lid opening confirmation key is depressed by the user and the lid opening member is operated, the lid opening confirmation key interferes with the lid opening member, such that the lid opening member cannot drive the lid 10 from the closed position to the open position. When the cover opening confirmation key is reset, the cover opening confirmation key and the cover opening member do not interfere with each other, and at this time, the cover opening member can drive the pot cover 10 to move from the closed position to the open position.
As shown in fig. 1 and 2, in the first embodiment, a panel 11 is provided on a pot body or a lid 10, and a lid opening operation portion is provided on the panel 11, the lid opening operation portion forming a lid opening confirmation key 30. After cooking is completed, the user can press the lid opening operation portion on the panel 11, and press the lid opening operation portion as the first trigger signal. When the cover opening confirmation key 30 receives the first trigger signal, the cover opening member 20 can drive the pot cover 10 to move from the closed position to the open position, so as to realize the cover opening. The structure is simple, and the operation of a user is convenient. Preferably, in the present embodiment, when the cooking is completed for a predetermined time or the pressure in the cooking cavity is less than the predetermined pressure, the position corresponding to the door opening operation portion on the panel 11 is lighted to remind the user that the door can be opened at this time.
In the first embodiment, the operation of pressing the door operation portion is used as the first trigger signal. However, the first trigger signal is not limited thereto, and may be a sound signal or an image signal. For example, the user emits a "cover opening" sound, which is a first trigger signal, and if the control board receives the sound signal, the cover opening member 20 drives the pot cover 10 from the closed position to the open position.
As shown in fig. 2 to 10, in the first embodiment, the pot cover 10 includes a face cover 12, an inner liner 13, and a rotatable inner cover sequentially disposed from outside to inside, and the cover opening member 20 drives the inner cover to rotate to move the pot cover 10 from the closed position to the open position.
In a first embodiment, as shown in fig. 2-10, an lid opener 20 is pivotally disposed on the liner 13 and is coupled to the inner lid to drive the inner lid in rotation relative to the liner 13. The structure is simple, and the opening and closing of the pot cover are easy to realize.
As shown in fig. 3 to 8, in the first embodiment, the cooking appliance further includes an electromagnet 40 and a stopper 50. Wherein, if the control board receives the second trigger signal, the control board can send a control signal to the electromagnet 40 to control the electromagnet 40 to be powered on or powered off. The stopper 50 is floatably provided, and when the electromagnet 40 is powered off, the stopper 50 can be stopped between the lid opening member 20 and the liner 13 to keep the lid opening member 20 in the initial position, and when the electromagnet 40 is powered on, the stopper 50 can be separated from the liner 13 under the action of magnetic force generated by the electromagnet 40 thereof to enable the lid opening member 20 to rotate. The structure is simple, the production cost is low, and the occupied space is small.
As shown in fig. 3 to 13, in the first embodiment, the cover opening member 20 includes a rotating rod 22, the rotating rod 22 is provided with a mounting hole 21, the stopper 50 is a float penetrating through the mounting hole 21, the liner 13 is provided with a clamping hole 131 opposite to the electromagnet 40, when the pot cover 10 is in the closed position, the mounting hole 21 can be coaxial with the clamping hole 131, the float can extend into the clamping hole 131 under the action of its own gravity, at this time, the user rotates the cover opening member 20, and the cover opening member 20 cannot rotate due to the fact that the side wall of the float abuts against the clamping hole 131, so that the cover opening member 20 can be kept in the initial position. The structure is simple and easy to process. When unlocking is needed, a user puts fingers on the cover opening operation part, the cover opening operation part sends a second trigger signal to the control board, the control board controls the electromagnet 40 to be electrified after receiving the second trigger signal, and the electromagnet 40 can attract the floater after being electrified so as to enable the floater to be far away from the clamping hole 131. Since the float is no longer abutted against the wall of the card hole 131, the user can smoothly rotate the lid opening member 20, and finally the lid opening is realized.
Since the float moves away from the electromagnet 40 gradually during rotation of the lever 22, the magnetic attraction generated between the electromagnet 40 and the float may not be sufficient to overcome the weight of the float itself when the lever 22 moves to a certain position, and the float will fall under its own weight. During continued rotation of the turning lever 22, the bottom of the float will come into contact with the inner liner 13. However, due to the complex structure of the liner 13 and the large number of ribs, the bottom of the float may interfere with the ribs on the liner during the rotation of the rotating rod, which results in unsmooth rotation of the rotating rod 22. In order to solve the above-mentioned problem, as shown in fig. 8 and 11, in the first embodiment, the inner liner 13 is provided with an arc-shaped rib 132, and the clamping holes 131 are provided on the upper surface of the arc-shaped rib 132. When the rotating rod 22 rotates to a predetermined position, the float falls down onto the upper surface of the smooth arc rib 132 under the action of gravity, and the above structure prevents the float from interfering with other structures during the rotation of the rotating rod, thereby improving the smoothness of the rotation of the rotating rod 22.
As shown in fig. 1 to 11, in the first embodiment, the electromagnet 40 has an energized state and a de-energized state. The stopper 50 is floatably provided, and if the electromagnet 40 is in the power-off state, the stopper 50 can be stopped between the lid opening member 20 and the lid cover 10 to keep the lid opening member 20 at the initial position, and if the electromagnet 40 is in the power-on state, the stopper 50 can be moved to a position not interfering with the lid cover 10 and/or the lid opening member 20 by the magnetic force generated by the electromagnet 40 thereof, so that the lid opening member 20 can drive the lid cover 10 to move from the closed position to the open position.
According to the first embodiment, the cooking appliance includes the electromagnet 40 and the stopper 50, and when the electromagnet 40 is powered off, the stopper 50 can be stopped between the lid opening member 20 and the lid 10. At this time, the cover 20 cannot be displaced relative to the pot cover 10 by the stopper 50, and thus the pot cover 10 cannot be driven to move from the closed position to the open position. When the electromagnet 40 is energized, the stopper 50 can move to a position not interfering with the lid 10 and/or the lid opening member under the magnetic force generated by the electromagnet 40. At this time, since the stopper 50 is no longer stopped between the lid opening member 20 and the lid 10, the lid opening member 20 can be displaced with respect to the lid 10, and thus the lid 10 can be driven to move from the closed position to the open position. In the structure, because the user needs to control the electromagnetic valve before opening the cover, namely, the on-off of the electromagnetic valve is controlled, the step of confirming whether the cover is opened or not is added before opening the cover, the scalding phenomenon caused by the incorrect cover opening of the user is prevented, and the problem of poor safety of the electric pressure cooker in the prior art is solved. In addition, the above structure is simple, and the production costs of the electromagnet 40 and the stopper 50 are low, so that the cooking appliance having the same is not only high in safety, but also low in production cost.
As shown in fig. 2 to 9, in the first embodiment, the pot cover 10 includes a cover 12, an inner liner 13 and a rotatable inner cover sequentially disposed from outside to inside, and the cover opening member 20 is pivotally disposed on the inner liner 13 and connected to the inner liner to drive the inner liner 13 to rotate, and if the electromagnet 40 is in an energized state, the stopper 50 can be moved to a position not interfering with the pot cover 10 and/or the cover opening member 20 by the magnetic force generated by the electromagnet 40 thereof, so that the cover opening member 20 can rotate. The structure is simple and easy to realize.
As shown in fig. 2 to 9, in the first embodiment, the lid opening member 20 includes a rotating rod 22, where the rotating rod 22 is pivotally disposed on the inner liner 13 and connected to the inner liner to drive the inner liner to rotate relative to the inner liner 13, a stopper 50 is floatably disposed on the rotating rod 22, and an electromagnet 40 is disposed on the inner liner 13 and above the stopper 50, and when the electromagnet 40 is in an energized state, the stopper 50 can be far away from the inner liner 13 under the action of magnetic attraction generated by the electromagnet 40. The structure is simple and easy to realize.
As shown in fig. 2 to 13, in the first embodiment, the rotating rod 22 is provided with a mounting hole 21, the stopper 50 is a float penetrating through the mounting hole 21, the liner 13 is provided with a clamping hole 131 opposite to the electromagnet 40, when the pot cover 10 is in the closed position, the mounting hole 21 can be coaxial with the clamping hole 131, and the float stretches into the clamping hole 131 under the action of its own gravity so as to keep the cover 20 in the initial position.
As shown in fig. 12 and 13, in the first embodiment, the rotating lever 22 includes a rotating lever body 221 and a lug 222 provided on a side wall of the rotating lever body 221, and the mounting hole 21 is provided on the lug 222. The structure is simple and convenient to process.
As shown in fig. 4, 5, 8 and 12, in the first embodiment, the float includes a clip column 51 and a ferromagnetic member 52 provided at a first end of the clip column 51, a lower surface of the ferromagnetic member 52 can abut against an upper surface of the lug 222 to prevent the float from falling out of the mounting hole 21 downward, an annular flange 511 is provided on a side wall of a second end of the clip column 51, an upper surface of the annular flange 511 can abut against a lower surface of the lug 222 to prevent the float from falling out of the mounting hole 21 upward, and a second end of the clip column 51 can extend into the clip hole 131. The structure is simple and convenient to assemble. Preferably, in the first embodiment, the ferromagnetic member 52 is a screw. The structure is simple and the cost is low.
As shown in fig. 5, 10, 11 and 14, in the first embodiment, a limiting structure 60 is provided between the electromagnet 40 and the lid 10 to limit the rotation of the electromagnet 40, and the electromagnet 40 is fixed to the lid 10 by a fastener 70.
According to the first embodiment, a limiting structure 60 capable of limiting the electromagnet 40 to rotate along the circumferential direction is arranged between the electromagnet 40 and the pot cover 10. When the electromagnet 40 is installed, the installer only needs to install the fastener 70 with one hand because the circumferential direction of the electromagnet 40 is already limited by the limiting structure 60. The above structure makes the installation of the electromagnet 40 simple and convenient, frees the other hand of the installer, improves the installation efficiency and reduces the labor intensity.
As shown in fig. 11 and 14, in the first embodiment, the limiting structure 60 includes a protrusion 61 and a recess 62 that are engaged with each other, one of the protrusion 61 and the recess 62 is provided on the lid 10, and the other of the protrusion 61 and the recess 62 is provided on the electromagnet 40.

When the electromagnet 40 is mounted, the electromagnet 40 is first turned so that the mounting hole on the electromagnet lug 42 is opposed to the mounting hole on the mounting post 133, and the projection 61 is opposed to the recess 62. The electromagnet 40 is then lowered so that the lower surface of the electromagnet lug 42 abuts the upper surface of the mounting post 133. Finally, the screws are screwed into the mounting holes on the electromagnet lugs 42 and the mounting holes on the mounting posts 133, so that the electromagnet 40 is fixed. When the screw is screwed, the electromagnet 40 has a tendency to rotate relative to the mounting post 133, the side wall of the projection 61 abuts against the wall of the groove 62 to restrict the electromagnet 40 from rotating.
