And since the spacer 40 exists between the elastic plate 30 and the heat preservation cover 10, the elastic plate 30 and the heat preservation cover 10 are not in direct contact. In addition, in the heating and cooling process of the pot body, the elastic plate 30 and/or the heat insulation cover 10 may deform in the sound insulation gap to different degrees due to the difference of heat transfer performance, the vibration frequency generated by deformation can be reduced by the isolating piece 40, collision of the elastic plate and the heat insulation cover is avoided, abnormal sound is avoided, and a user obtains better experience.

The gap in the above structure provides enough space for the deformation of the elastic plate 30, and at the same time, the support member 22 and the heat-retaining cover 10 are not contacted, so that the heat-generating device 20 is prevented from directly transferring heat to the heat-retaining cover 10 via the support member 22, and the heat transfer is slowed down. The term "plurality" as used herein includes two or more.

As shown in fig. 2 to 6, the bottom surface of the first support column includes a first abutment inclined surface 221, and the bottom surface of the second support column includes a second abutment inclined surface, and both the first abutment inclined surface 221 and the second abutment inclined surface are disposed obliquely in a direction from the connecting member 21 to the connecting member 21. The heat generating device 20 is in a non-pressurized state and the heat generating device 20 is transferred to the elastic plate 30 at a lower speed than the speed at which the entire bottom surfaces of the first support column and the second support column contact-transfer to the elastic plate 30 by the smaller area where the first contact slope 221 and the second contact slope contact the elastic plate 30.

In this way, the heat generating device is in abutting engagement with the elastic plate 30 in an unpressurized state by both the first abutting plane 222 and the second abutting plane. The heat generating device is in a pressed state, the elastic plate 30 is deformed upward, and the elastic plate 30 is supported to the first abutment inclined surface 221 and the second abutment inclined surface. The width of the first abutment plane 222 and the width of the second abutment plane are both preferably 1.5mm; the inclination angle of the first abutment inclined surface 221 and the inclination angle of the second abutment inclined surface are each preferably 4 °, and the maximum drop of the first abutment inclined surface 221 and the second abutment inclined surface is each preferably 0.3mm.

The fastener 13 comprises a screw and a spring gasket sleeved on the screw, the connecting hole 211 is a screw hole, and the screw passes through the first through hole 11 from bottom to top and is connected in the screw hole.

In a more preferred embodiment, the connecting piece 21 is directly connected with the fastener 13, so as to form a fixed connection with the heat insulation cover 10, the connecting piece 21 is not in direct contact with the elastic plate 30, the isolating piece 40 and the heat insulation cover 10, so that the heat conduction path of the heat generating device 20 to the outside is reduced, and the heat transfer is further reduced; the heat of the heating device 20 can be transferred to the elastic plate only through the supporting piece in a heat conduction mode, and then the elastic plate is transferred to the heat insulation cover through the isolating piece, so that a sound insulation gap formed between the elastic plate and the heat insulation cover not only provides a buffer space, collision between parts is avoided, but also provides a heat conduction limiting means, the direct contact area between the elastic plate and the heat insulation cover is reduced, when the temperature of the cooker body changes, the heat transfer is slowed down, the material is prevented from being deformed obviously due to rapid change of the heat as much as possible, the probability and the sound intensity of abnormal sound during cooking of the electric pressure cooker are reduced, the scheme is easy to implement, and the technical problem that the industry is always desirous of solving but is always unsuccessful is solved with extremely low cost.

The heat insulating cover 10 is provided with a convex portion 12 protruding upward at a position where the bottom of the connecting member 21 is connected, and the spacer 40 is sandwiched between the elastic plate 30 and the convex portion 12 so that a sound insulation gap is formed between the elastic plate 30 and the convex portion 12. When the cooking utensil is cooked, the inner pot and the heating device are pushed by the high pressure gas in the inner pot to move downwards and press against the elastic plate, and the elastic plate transmits the pressure from the inner pot to the bottom wall of the heat preservation cover through the isolating piece 40. Because the elastic plate has elasticity and can deform when being pressed, the pressure of part from the inner pot can be counteracted, and the heat preservation cover is protected. The setting of convex part can increase the structural strength of heat preservation cover bottom, reduces the deflection after the heat preservation cover is pressed. And the convex part is indirectly contacted with the elastic plate through the isolating piece 40, so that the direct contact area between the elastic plate and the heat preservation cover can be reduced, and the heat transfer is slowed down when the temperature of the pot body changes.

Of course, in an embodiment not shown in the figures, the pan body also comprises an inner pan arranged above the heat generating means. Or the heat preservation cover is provided with a convex part protruding upwards at the position where the heat preservation cover is connected with the bottom of the connecting piece, and the isolation piece is clamped between the elastic plate and the convex part, so that a sound insulation gap is formed between the elastic plate and the convex part.
