[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] See also Figure 1 The utility model discloses an electric pressure cooker. The electric pressure cooker of this embodiment is an electromagnetic induction electric pressure cooker. The electromagnetic induction heating speed is faster than that of a traditional pressure cooker, and the heating is more uniform. Since the electromagnetic heating pressure cooker has a fast heating speed and is more energy-efficient than a traditional pressure cooker, it can significantly improve the cooking efficiency when used.

[0029] The electric pressure cooker of this embodiment includes a pot cover 1, an outer pot 2, an inner pot 3 and an elastic component. The pot teeth of the pot cover 1 are buckled with the pot teeth of the outer pot 2, so that a receiving cavity is formed between the pot cover 1 and the outer pot 2, and the inner pot 3 is accommodated in the receiving cavity. The elastic component is arranged at the bottom of the outer pot 2 and abuts against the bottom of the inner pot 3 to withstand the pressure of the inner pot 3. With such a design, the pot teeth of the pot cover 1 are buckled with the pot teeth of the outer pot 2 to achieve pressure bearing on the upper side of the electric pressure cooker, and the inner pot 3 can be made very thin to meet the requirement of low cost. The elastic component is arranged between the bottom of the outer pot 2 and the bottom of the inner pot 3 to withstand the pressure of the inner pot 3, which can achieve pressure bearing on the lower side of the electric pressure cooker, and can avoid the problem of plastic deformation of the inner pot 3 and the outer pot 2 due to pressure bearing, so that the electric pressure cooker of this scheme meets the safety requirements while meeting the low cost.

[0030] Please also read Figures 2 to 5 In some embodiments, the elastic assembly includes a plurality of support members 41 and a plurality of elastic elements 42. The plurality of support members 41 are arranged at intervals at the bottom of the outer pot 2. Each elastic element 42 is arranged on a support member 41. The bottom of the inner pot 3 abuts against the elastic element 42. The elastic element 42 is used to elastically deform relative to the support member 41 when subjected to the pressure of the inner pot 3. With such a design, when the inner pot 3 is subjected to pressure, the inner pot 3 will move downward under the action of the internal pressure due to the engagement of the pot cover 1 with the pot teeth of the outer pot 2, squeezing the elastic element 42 to cause the elastic element 42 to elastically deform. That is, the elastic element 42 can buffer the pressure of the inner pot 3, thereby preventing the pressure of the inner pot 3 from directly acting on the outer pot 2. When the pressure inside the inner pot 3 is released, the elastic element 42 is reset and drives the inner pot 3 to move upward, thereby achieving the reset of the inner pot 3.

[0031] This embodiment is illustrated by taking the example that there are three support members 41 and three elastic members 42, and the three support members 41 and three elastic members 42 are arranged around the outer periphery of the outer pot 2. In other embodiments, two or four support members 41 and elastic members 42 may also be used as an example, which is not limited here.

[0032] The elastic element 42 is made of manganese steel. With this design, since manganese steel has good elasticity, the elastic element 42 has good elasticity after being stressed, and can withstand reciprocating deformation for a long time without plastic deformation.

[0033] Furthermore, in order for the elastic element 42 to be displaced and reset relative to the support member 41, the support member 41 includes two support ribs 411, which are arranged at intervals, and the elastic element 42 is a long block structure, with both ends of the elastic element 42 overlapping the two support ribs 411. With such a design, since both ends of the elastic element 42 overlap the two support ribs 411 arranged at intervals, when the inner pot 3 is displaced downward under the action of the internal pressure, the middle part of the elastic element 42 elastically deforms downward, and when the pressure inside the inner pot 3 is released, the middle part of the elastic element 42 is reset and drives the inner pot 3 to move upward, thereby realizing the reset of the inner pot 3.

[0034] Among them, the two support ribs 411 are integrally formed on the outer pot 2. It can be understood that in other embodiments, the design method of installing the two support ribs 411 on the outer pot 2 can also be adopted, which is not limited here.

[0035] In some embodiments, since the elastic elements 42 are arranged in multiple intervals, in order to support the inner pot 3 more stably, the elastic component further includes a support ring 43, which is arranged on and covers the multiple elastic elements 42, and the bottom of the inner pot 3 abuts against the support ring 43. With such a design, when the inner pot 3 is subjected to pressure, the inner pot 3 will move downward under the action of the internal pressure and push the support ring 43 downward, and the support ring 43 squeezes the elastic element 42 to make the elastic element 42 elastically deformed. When the pressure inside the inner pot 3 is released, the elastic element 42 is reset and drives the support ring 43 and the inner pot 3 to move upward, thereby realizing the reset of the inner pot 3.

[0036] Furthermore, the support ring 43 is extended in the direction toward the bottom of the outer pot 2 to form a plurality of limiting ribs 431, and the limiting ribs 431 are formed with limiting grooves 432, and each elastic element 42 is respectively accommodated in a limiting groove 432. With such a design, the relative position of the support ring 43 and the elastic element 42 can be limited.

[0037] Please also read Figures 3 to 6 In some embodiments, the electric pressure cooker further comprises an electromagnetic heating device 5 for heating the food in the inner pot 3, which is fixed on the support ring 43 and located at the bottom of the inner pot 3. With such a design, the inner pot 3 will move downward under the internal pressure, pushing the support ring 43 downward. Since the electromagnetic heating device 5 is fixed on the support ring 43, the coil rack 51 and the electromagnetic heating device 5 move downward with the support ring 43 to ensure the distance between the electromagnetic heating device 5 and the inner pot 3, thereby ensuring that the electromagnetic heating device 5 can maintain a stable heating effect.

[0038] Furthermore, a mounting avoidance opening 21 is provided in the middle area of ​​the bottom of the outer pot 2, the electromagnetic heating device 5 is located at the mounting avoidance opening 21, and a plurality of support members 41, a plurality of elastic elements 42 and a support ring 43 are arranged around the outer periphery of the corresponding mounting avoidance opening 21 of the outer pot 2. With such a design, the support members 41, the elastic elements 42, the support ring 43 and the outer pot 2 can be prevented from affecting the use effect of the electromagnetic heating device 5.

[0039] Furthermore, the electromagnetic heating device 5 includes a coil frame 51 and a coil 52. The coil frame 51 is located at the installation avoidance opening 21 and fixed on the support ring 43. The coil 52 is installed on the coil frame 51. With such a design, the inner pot 3 will move downward under the internal pressure, pushing the support ring 43 and the elastic element 42 to move downward, and the coil frame 51 moves downward with the support ring 43, and at the same time drives the coil frame 51 to move downward, so as to ensure the distance between the electromagnetic coil 52 and the inner pot 3.

[0040] In some embodiments, in order to achieve a fixed connection between the coil frame 51 and the support ring 43, the coil frame 51 extends outward to form a connecting ear 511, and a first connecting hole 512 is provided on the connecting ear 511. The support ring 43 extends toward the connecting ear 511 to form a connecting column 433, and a second connecting hole 434 is provided on the connecting column 433. The electric pressure cooker also includes a connecting member 6, one end of the connecting member 6 passes through the first connecting hole 512 and is connected to the second connecting hole 434, and the other end presses the connecting ear 511.

[0041] Furthermore, the connecting ear 511 is located at the bottom of the outer pot 2 and is arranged corresponding to the elastic element 42, the elastic element 42 is provided with a first avoidance hole 421, the outer pot 2 is provided with a second avoidance hole 22, and the connecting column 433 passes through the first avoidance hole 421 and the second avoidance hole 22. With such a design, the support ring 43, the elastic element 42, the outer pot 2 and the outer disk of the coil 52 are connected through the connecting column 433 and the connecting lug, so that the structure is more compact.

[0042] The utility model provides an electric pressure cooker, which includes a pot cover 1, an outer pot 2, an inner pot 3 and an elastic component.
