Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are intended to be illustrative of the invention and are not to be construed as limiting.

An electric cooking apparatus according to an embodiment of the present invention may be described in detail below with reference to the accompanying drawings, which may be a rice cooker, an electric pressure cooker, an electric cooker, or the like.

An electric cooking apparatus according to an embodiment of the present invention may include: a body, a lid 10, a plugging structure 20, a push rod 30, a magnetic component, and an elastic device, the cooking chamber is defined in the body, and the lid 10 is disposed on the body The cooking chamber is opened or closed, and the pressure cover 11 is provided on the lid 10, wherein the pressure relief port 11 communicates with the cooking chamber. The plugging structure 20 opens the pressure relief port 11 under the action of its own gravity, the driving device is disposed on one side of the plugging structure 20, and the driving device is used to drive the plugging structure 20 to close the pressure releasing port 11. For example, the occlusion structure 20 has an open position and a sealed position. When the occlusion structure 20 is in the open position, the occlusion structure 20 releases the seal to the pressure relief port 11. When the occlusion structure 20 is in the sealed position, the occlusion structure 20 Seal the pressure relief port 11. Alternatively, the plugging structure 20 can be a sphere.

Moreover, in the up and down direction, the sealing position is higher than the open position, so that the blocking structure 20 is adapted to move from the sealing position to the open position by the action of its own weight to open the pressure relief opening 11. It can be understood that when the driving device keeps driving the blocking structure 20, the blocking structure 20 is maintained in the sealing position, and when the driving device releases the driving of the blocking structure 20, the blocking structure 20 can move under the action of gravity. To the open position, the electric cooking device begins to relieve pressure. In this way, the electric cooking device can realize the instantaneous pressure relief, so that the food can be tumbled, the agglomeration of the food can be avoided, and the taste of the food can be improved.

Specifically, the push rod 30 is disposed at one side of the plugging structure 20, and the magnetic component includes: a first magnetic member 40 and a second magnetic member, at least one of the first magnetic member 40 and the second magnetic member is an electromagnetic member, A magnetic member 40 is mounted on the flip cover 10 and a second magnetic member is mounted on the push rod 30. It can be understood that when only one magnetic component is a magnetic component, the first magnetic component 40 can be an electromagnetic component, or the second magnetic component can be an electromagnetic component; when the magnetic component has two electromagnetic components, the first magnetic component Both the 40 and the second magnetic member are electromagnetic members. Preferably, as shown in FIG. 1, the first magnetic member 40 is an electromagnetic member, the first magnetic member 40 is fixed on the flip cover 10, and the second magnetic member may be a metal member or magnet having magnetic properties. The second magnetic member may be a metal member such that the first magnetic member 40 can magnetically adsorb the second magnetic member when the first magnetic member 40 is in an energized state.

The elastic device elastically presses the push rod 30 and/or the second magnetic member to keep the sealing structure 20 in the sealing position (ie, the pressure relief port position) under the elastic force to close the pressure relief port 11, which is understandable. Yes, the elastic means can elastically press the push rod, or the elastic means can elastically press against the second magnetic member, or the elastic means can elastically press the push rod and the second magnetic member, wherein when the electromagnetic member is energized, A magnetic attraction force is generated between the first magnetic member 40 and the second magnetic member, and the magnetic attraction force at least partially offsets the elastic force to move the sealing structure 20 to the open position, that is, the sealing structure 20 opens the pressure relief port 11 under the action of its own gravity. . It can be understood that when the first magnetic member 40 is not energized, the elastic device pushes the second magnetic member and the push rod 30 to the right, so that the push rod 30 can push the sealing structure 20 to the sealing position when the first magnetic member After energization of 40, a magnetic attraction force is generated between the first magnetic member 40 and the second magnetic member, so that the second magnetic member can move toward the first magnetic member 40 against the elastic force of the elastic device until the second magnetic member is attracted to the first magnetic member. At 40, at this time, the blocking structure 20 is moved from the sealing position to the open position, so that the cooking chamber can be instantly relieved of pressure, the food can be tumbled, the agglomeration of the food can be avoided, and the taste of the food can be improved. Wherein, the elastic device may be a spring, and both ends of the spring may stop between the first magnetic member 40 and the push rod 30.

Among them, in order to better simplify the structure of the electric cooking device, as shown in FIG. 1, the push rod 30 and the second magnetic member are the same member. In other words, the push rod 30 can be made of a metal piece, or the push rod 30 can be a magnet.

Optionally, as shown in FIG. 1 , the electric cooking device may further include: a flexible member 50 , the flexible member 50 is sleeved on the push rod 30 , and the flexible member 50 is stopped on the sealing structure 20 . As shown in FIG. 1, the flexible member 50 is formed with a groove, the groove is open toward the push rod 30, and the outer edge of the groove can be mounted on the cover 10, and the bottom of the groove can form a limit groove, and the end of the push rod 30 The part can be inserted into the limit slot. Thus, the flexible member 50 is disposed between the push rod 30 and the sealing structure 20, so that the push rod 30 and the sealing structure 20 can be effectively spaced apart, and when the cooking chamber is released, steam cannot act on the push rod 30, thereby Raise the putter The service life of 30 can improve the working reliability of the electric cooking device. Alternatively, the flexible member 50 may be a heat resistant rubber member.

As shown in FIG. 1, the cover 10 may be provided with a seat body 12, and a pressure relief port 11 is formed on the seat body 12. The blocking structure 20 is disposed on the upper surface of the seat body 12, and the upper surface of the seat body 12 is inclined so that The plugging structure 20 is moved to the open position by its own gravity when the electromagnetic member is in an energized state. It can be understood that, when the first magnetic member 40 is energized, the second magnetic member and the push rod 30 are attracted to the first magnetic member 40, and the blocking structure 20 can be moved from the sealing position to the opening under the force of its own gravity. The position is such that the occlusion structure 20 can be moved from the sealing position to the open position by properly arranging the upper surface of the seat body 12, so that the electric cooking device can be realized in a simple manner and has a simple structure.

Wherein, optionally, the angle between the upper surface of the base 12 and the horizontal plane may be 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 that satisfies the above range can cause the plugging structure 20 to roll naturally, so that switching of the plugging structure 20 between the sealed position and the open position can be easily achieved.

Specifically, as shown in FIG. 1, the base 12 may further include a baffle 60 opposite the driving device and configured to stop the sealing structure 20 in a sealed position. For example, the baffle 60 is opposite to the push rod 30. When the plugging structure 20 is in the sealing position, the two sides of the plugging structure 20 respectively stop against the baffle 60 and the push rod 30, and the baffle 60 can effectively prevent the push rod 30 Pushing the plugging structure 20 away from the pressure relief port 11 can ensure the sealing reliability of the electric cooking device, thereby improving the operational reliability of the electric cooking device. Preferably, the height of the baffle 60 may be no higher than the center of the plug structure 20. This can at least partially save material for the seat 12 and can cause the baffle 60 to oppose the push rod 30 so that both the push rod 30 and the baffle 60 can collectively restrain the occluding structure 20 in the sealed position.

According to the electric cooking device of the embodiment of the present invention, when the first magnetic member 40 is energized, a magnetic attraction force is generated between the first magnetic member 40 and the second magnetic member, so that the second magnetic member can overcome the elastic force of the elastic device. Moving to the first magnetic member 40 until the second magnetic member is adsorbed on the first magnetic member 40, at this time, the blocking structure 20 is moved from the sealing position to the open position, so that the cooking chamber can be instantly relieved, and the food can be tumbled. It can avoid the agglomeration of food and can improve the taste of food.
