Detailed Description

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

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: the cooker comprises a cooker body, a cooker cover 10, a magnetic blocking structure 20, an electromagnetic driving device 30 and a stop piece.

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 electromagnetic driving device 30 is disposed on one side of the magnetic blocking structure 20, and the electromagnetic driving device 30 is adapted to generate a magnetic force in a 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 may be used to close the pressure relief opening 11, and the electromagnetic driving device 30 may control the closed state of the pressure relief opening 11, in other words, the electromagnetic driving device 30 may change the position of the magnetic blocking structure 20 by controlling the on-off state of itself to change the opening and closing of the pressure relief opening 11.

For example, when the electromagnetic driving device 30 is in the energized state, the electromagnetic driving device 30 generates a magnetic attraction force, so that the magnetic blocking structure 20 can be magnetically attracted above the pressure relief opening 11 to close the pressure relief opening 11.

The stop is arranged at the pressure relief opening 11, in particular, near the pressure relief opening, and is adapted to stop the magnetic blocking structure 20 closing the pressure relief opening 11. It can be understood that when the electromagnetic driving device 30 adsorbs the ferromagnetic blocking structure 20 to the position right above the pressure relief opening 11, so that the magnetic blocking structure 20 closes the pressure relief opening 11, and then the magnetic blocking structure 20 abuts against the abutting member, so that the abutting member can facilitate the magnetic blocking structure 20 to keep the closed position closing the pressure relief opening 11.

Moreover, after the electric cooking device works for a period of time, the pressure in the cooking cavity is gradually increased, and the magnetic blocking structure 20 is also suitable for releasing the blocking of the blocking piece away from the pressure relief opening 11 under the steam pressure effect of the pressure relief opening 11. That is to say, the magnetic blocking structure 20 can open the pressure relief opening 11 in a passive manner pushed by the steam pressure of the pressure relief opening 11 without any active manner, so that instant pressure relief of the electric cooking device can be realized, caking of food can be avoided, and the taste of the food can be improved. And thus, the control of the control unit can be omitted and the cost of the electric cooking apparatus can be reduced.

Therefore, the electric cooking device is simple in structure, simple to control and low in cost.

Further, the electromagnetic drive device 30 is adapted to energize to generate a magnetic force after the magnetic blocking structure 20 is moved away from the pressure relief opening 11, so that the magnetic blocking structure 20 re-closes the pressure relief opening 11. Therefore, the automatic bumping can be realized after a certain pressure value is reached by repeating the steps for 3-5 times, and the control of a control unit is not needed.

Alternatively, the electromagnetic drive 30 may be an electromagnetic disc and the magnetic blocking structure 20 may be a magnet.

Specifically, as shown in fig. 1, a base 12 is disposed on the pot lid 10, a pressure relief opening 11 is formed on the base 12, and a magnetic blocking structure 20 is disposed on an upper surface of the base 12, wherein the upper surface of the base 12 is substantially inclined so that the magnetic blocking structure 20 releasing the stopping of the stopping member is away from the pressure relief opening 11 under the action of its own gravity. 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, from one end far away from the electromagnetic driving device 30 to the other end near the electromagnetic driving device 30, the distance from the upper surface of the base 12 to the lower surface of the pot cover 10 is increased and then decreased, and the pressure relief opening 11 is disposed near the other end of the upper surface of the base 12. That is to say, a point with the largest distance to the lower surface of the cooker cover 10 can be formed in the middle area of the upper surface of the base 12, so that when the magnetic blocking structure 20 closes the pressure relief opening 11, the point can play a role of supporting and limiting at least to a certain extent, thereby ensuring that the magnetic blocking structure 20 is kept at the closed position of the closed pressure relief opening 11 under the action of gravity, further better improving the pressure maintaining reliability of the electric cooking device, and improving the working reliability of the electric cooking device.

Specifically, as shown in fig. 1, the stopping member is disposed on the base 12, and the stopping member is a step 121, the distance from the end of the step 121 to the lower surface of the pot cover 10 is the largest, and the magnetic blocking structure 20 stops against the step 121 when the magnetic blocking structure 20 closes the pressure relief opening 11. The step 121 may function to support the magnetic blocking structure 20 in the closed position.

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.

Preferably, as shown in fig. 1, the magnetic blocking structure 20 may be a sphere, and the height of the baffle 122 is not higher than the center of the magnetic blocking structure 20. In this way, the end of the flap 122 can be better supported on the magnetic closure structure 20, so that the reliability of the magnetic closure structure 20 above the pressure relief opening 11 can be better ensured.
