An electric cooking apparatus, which may be an electric rice cooker, an electric pressure cooker, an electric stewpot, and the like, according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, an electric cooking apparatus according to an embodiment of the present invention may include: a pot body, a pot cover 10, a magnetic blocking structure 20 and an electromagnetic driving device 30.
A cooking cavity is limited in the cooker body, a cooker cover 10 is arranged on the cooker body to open or close the cooking cavity, and a pressure relief opening 11 is formed in the cooker cover 10, wherein the pressure relief opening 11 is communicated with the cooking cavity. The magnetic blocking structure 20 can open the pressure relief opening 11 under the action of its own gravity, the electromagnetic driving device 30 is disposed at one side of the magnetic blocking structure 20, and the electromagnetic driving device 30 is adapted to generate a magnetic force under the power-on state to enable the magnetic blocking structure 20 to close the pressure relief opening 11. It is understood that the magnetic blocking structure 20 can be used for closing and opening the pressure relief opening 11, and the electromagnetic driving device 30 can control the open and closed state of the pressure relief opening 11, in other words, the electromagnetic driving device 30 can change the position of the magnetic blocking structure 20 by controlling the on-off state of the electromagnetic driving device 30 to change the open and closed state of the pressure relief opening 11.
When the electromagnetic driving device 30 is in the power-on state, the electromagnetic driving device 30 generates a magnetic force, so that the magnetic blocking structure 20 can be magnetically attracted to the upper side of the pressure relief opening 11 to close the pressure relief opening 11. When the electromagnetic driving device 30 is in the off state, the magnetic blocking structure 20 can move from the closed position for closing the pressure relief opening 11 to the open position for opening the pressure relief opening 11 under the action of the gravity of itself after the action of no magnetic force, so that the pressure relief of the cooking cavity can be realized. The electric cooking device can realize instant pressure relief, so that food can roll, caking of the food can be avoided, and the taste of the food can be improved. And through the cooperation of electromagnetic drive device 30 and magnetism block structure 20, can make electric cooking device pressure release easy operation, simple structure, it is with low costs. Through the arrangement, compared with the traditional mode that the magnetic plugging structure 20 is pushed by the push rod, the push rod through hole and the sealing device are prevented from being formed in the movable cavity wall of the magnetic plugging structure 20, the structure is simpler, and the cleaning is easier; electromagnetic drive device 30 also need not to set up to the active structure to avoid blocking the risk of makeing mistakes, also can be safer in addition, can guarantee that the pressure release mouth is normally opened in the outage.
Alternatively, the electromagnetic driving device 30 may be an electromagnetic disc, and the magnetic blocking structure 20 may be a metal piece or a magnet.
Specifically, as shown in fig. 1, a base body 12 is disposed on the pot lid 10, a pressure relief opening 11 is formed on the base body 12, a magnetic blocking structure 20 is disposed on an upper surface of the base body 12, the upper surface of the base body 12 is disposed obliquely so that the magnetic blocking structure 20 opens the pressure relief opening 11 under the action of its own gravity, and the magnetic force may be magnetic attraction force. The upper surface of the seat 12 disposed obliquely can facilitate the magnetic blocking structure 20 to roll smoothly thereon, so that the pressure relief switching of the electric cooking apparatus can be fast, and the working reliability of the electric cooking apparatus can be ensured.
According to a preferred embodiment of the present invention, as shown in fig. 1, the distance from the upper surface of the base 12 to the lower surface of the pot cover 10 gradually increases from one end far away from the electromagnetic driving device 30 to the other end near the electromagnetic driving device 30, and the pressure relief opening 11 is disposed near the other end of the upper surface of the base 12. Thus, when the electromagnetic driving device 30 is in the power-off state, the magnetic blocking structure 20 can move in a direction away from the electromagnetic driving device 30, so that the pressure relief opening 11 can be opened, and when the electromagnetic driving device 30 is in the power-on state, the electromagnetic driving device 30 can attract the magnetic blocking structure 20 to the upper side of the pressure relief opening 11, so that the pressure relief opening 11 can be closed. It should be noted that the lower surface of the pot cover 10 herein can be understood as the lower surface of the cover plate of the pot cover closing the cooking cavity.
Preferably, as shown in fig. 1, the upper surface of the holder body 12 may be an inclined plane. Thus, the magnetic blocking structure 20 smoothly rolls on the upper surface of the base 12, so that the electric cooking device is smoothly switched between the pressure maintaining state and the pressure releasing state, and the working reliability of the electric cooking device can be improved.
Preferably, the pot cover 10 is connected with the pot body in a hinged manner, the lower end of the upper surface of the base body 12 is close to the hinged end, and the higher end of the upper surface of the base body 12 is far away from the hinged end. Therefore, noise caused by rolling of the magnetic blocking structure 20 during opening of the cover can be reduced, and the magnetic blocking structure 20 can be positioned at the lower end of the inclined upper surface of the base body 12 no matter in the cover closing state or the cover opening state as long as the electromagnetic driving device 30 is powered off.
Optionally, as shown in fig. 1, the angle between the upper surface of the seat body 12 and the horizontal plane is between 0 ° and 45 °. Preferably, the angle between the upper surface of the seat body 12 and the horizontal plane may be 20 °. The upper surface of the seat body 12 satisfying the above range can make the magnetic blocking structure 20 roll naturally, so that the switching of the magnetic blocking structure 20 between the closed position and the open position can be easily realized.
Optionally, as shown in fig. 1, the seat body 12 may further include: a stop plate 122 opposite the electromagnetic drive 30, the stop plate 122 serving to stop the magnetic blocking structure 20 in the closed position. The baffle 122 can play a role in limiting the position of the magnetic blocking structure 20 to at least a certain extent, so that the reliability of the magnetic blocking structure 20 above the pressure relief opening 11 can be ensured, and the working reliability of the electric cooking device can be improved.
