The present invention relates to an electric pressure thermal rice cooker, in particular provided with a damping member in the main body or cover to the electric pressure thermal rice cooker to reduce the opening shock by effectively reducing the rotational acceleration of the cover when the cover is opened to the body It is about.

Generally, as shown in FIGS. 1A and 1B, the electric pressure thermal rice cooker is composed of two parts, the main body 4 and the cover 1, and the two parts are hinges including a hinge shaft 3 at the rear of the rice cooker. It is coupled to the structure while the cover 1 is opened and closed while rotating at a predetermined angle based on the hinge axis (3).

The hinge shaft (3) is provided with a torsion spring (2) by the elastic force of the torsion spring (2) to keep the cover (1) in an open state at an angle, when closing the cover (1) to the front It is fixed by the positioned open button 5 and remains closed until the open button 5 is pressed.

The cover (1) should be kept open at a certain angle or more when opened, less discomfort when taking out and put the food or inner pot inside the cooker.

Therefore, one of the important factors to determine the elastic force of the torsion spring (2) is the restoring force enough to support the weight of the cover (1), the other is the friction force and the cover ( 1) It is a torque enough to lift the cover (1) by overcoming the inertia force by weight.

Usually the torque of the two elements is greater, so the elastic force of the torsion spring 2 is designed to be more than the torque.

The conventional electric pressure thermal cooker is pressed when the opening button 5 in the closed state is released while the rotation force is generated around the hinge shaft (3) by the elastic force of the torsion spring (2) to open the cover (1).

At this time, the rotational force acting shows different rotational acceleration according to the operation angle of the cover 1, and the largest opening acceleration is shown because the angle of opening in the closed state of the cover 1 is the largest, and thus the rotational force is also the largest.

If the rotational force is large, the energy remains even after the cover 1 is completely opened to impact the cover 1 or the main body 4, so that the rice cooker is seen as a sway and shaking phenomenon.

As such, excessive rotational force may accumulate as a shock and may cause a problem in which the product is broken, and since the product is quickly opened, there is a problem that may cause injury to the user or damage to the product or the object when the user or the surrounding object is hit.

The present invention is proposed to solve the above problems, the purpose of which is to provide a damping member to the main body or cover to reduce the opening impact by effectively reducing the rotational acceleration of the cover when the cover is opened to the body It is to provide an electric pressure thermostat rice cooker.

That is, when the cover 1 is opened and the stopper part 1a formed on the cover 1 presses the damping member 6 fixed by the fixing screw 9 of the hinge cover 8, the cover is absorbed while the shock is absorbed. By reducing the rotational acceleration in (1), the rotational force is weakened so that the impact is alleviated.

At this time, the damping member 6 is supported at one end by the cylinder 6a, the elastic member 6b provided in the cylinder 6a, and the elastic member 6b, as shown in Figs. 6A and 6B. The other end includes a damping rod 6c exposed to the outside of the cylinder 6a.
