Problems solved by technology

[0003] The technology of electromagnetic or electric push rod requires a large space because the parts are moving devices, which restricts the appearance design, and the quality and reliability of the product are greatly affected by the production process and the processing accuracy of parts; as a solenoid valve technology , not only the cost increases more, but also the structure and manufacturability of the product are more complicated
And the above two schemes both exist, the pressure limiting value of the electric pressure cooker is a constant value due to the limitation of the pressure limiting valve body, so that when the two schemes operate, the inside of the electric pressure cooker is completely connected with the environmental space, releasing the pressure in the pot, Either completely isolated to maintain the set working pressure in the pot; the stepless adjustment of the limit pressure value cannot be realized to ensure that the electric pressure cooker always maintains low-pressure exhaust boiling cooking under the pressure lower than the rated limit pressure value.

Embodiment 1

[0025] Such as figure 1 ∽ Figure 4 As shown, the electric pressure cooker (99) of the present invention includes a pot cover (1) fastened on the pot body (2), and is installed on the pot cover (1), and the center is provided with an exhaust pipe (13) The circular electromagnetic chuck electromagnet (12) that passes hole, exhaust pipe (13) and magnetic force valve valve body (11).

[0026] Exhaust pipe (13) passes the center hole of electromagnet (12) and is installed on the pot cover (1), and magnetic force valve body (11) is movably sleeved on the exhaust pipe (13), and can be moved along the exhaust pipe (13). ) axial movement, the bottom of the magnetic valve body (11) is located above the electromagnet (12), and is on the same side as the unshielded end of the electromagnet (12).

[0027] When the coil (122) of the electromagnet (12) has no current flowing through it, the pressure limit value of the electric pressure cooker (99) is derived from the self weight of the ma...

Embodiment 2

[0031] Such as figure 1 ∽ Figure 4 As shown, the electric pressure cooker (99) of the present invention includes a pot cover (1) fastened on the pot body (2), and is installed on the pot cover (1), and the center is provided with an exhaust pipe (13) Circular magnetic chuck solenoid (12) through hole, exhaust pipe (13) and ferrite gravity valve body (11).

[0032] The exhaust pipe (13) passes through the center hole of the electromagnet (12) and is installed on the pot cover (1). The pipe (13) moves axially, and the ferrite gravity valve body (11) is on the same side as the unshielded end of the electromagnet (12).

[0033] When the coil (122) of the electromagnet (12) has no current flowing through it, the pressure limit value of the electric pressure cooker (99) is derived from the self weight of the ferrite gravity valve body (11), and the electric pressure cooker (99) is at this moment When heating continuously, the thimble of the ferrite gravity valve body (11) and th...

Abstract

The invention discloses an electric pressure cooker with a pressure limiting value controlled by an electromagnet. The electric pressure cooker comprises a cooker cover, a cooker body, the electromagnet, a vent pipe and a valve, and the electromagnet, the vent pipe and the valve are mounted on the cooker cover. The electric pressure cooker is characterized in that a hole allowing penetration of the vent pipe is formed in the center of the electromagnet, the vent pipe penetrates through the electromagnet and is mounted on the cooker cover, and the valve is arranged above the electromagnet, sleeves the vent pipe and is capable of moving axially along the vent pipe. The electric pressure cooker with the pressure limiting valve controlled by the electromagnet is fashionable in appearance, simple in structure, reliable in scheme and capable of realizing stepless adjustment of the pressure limiting value of the electric pressure cooker, by means of selecting a function before cooking, high-pressure and low-pressure adjustment selection of working pressure of the electric pressure cooker, optional switching between high working pressure and low working pressure during cooking and automatic air venting and quick uncovering after cooking can be finished automatically, and experience feel and cooking performance of an existing electric pressure cooker can be promoted and improved comprehensively by intelligentized means.

Description

technical field [0001] The invention relates to the technical field of electric heating cooking utensils, in particular to an electric pressure cooker which uses electromagnets to realize automatic control and adjust the pressure limit value. Background technique [0002] At present, with the development of the electric pressure cooker, in order to improve the cooking performance of the electric pressure cooker, or to realize intelligent quick opening, the prior art mainly adopts the following methods to realize. One is to drive the pressure-limiting valve body with an electromagnetic or electric push rod, so that the interior of the electric pressure cooker is connected or isolated from the environmental space, such as the patent of "an automatic exhaust electric pressure cooker" patent No. 201220217624.5; the second is between the pressure-limiting valve In addition, a solenoid valve is added to realize the control of the connection or isolation between the interior of the...
