It relates to a prevention device.

In general, unlike a general pressure cooker that increases the sealing force in the pot and cooks food (especially cooking function) that is difficult to cook at normal pressure, the electric heat pressure cooker converts electrical energy into thermal energy and then raises the pressure. Refers to a pot that automatically cooks rice, according to the alternative configuration is mainly the bottom of the bottom surface of the pot body is a heating element that can be heated to a predetermined temperature is built, the hinge hinges to be opened and closed tightly with the body Various steam discharge devices and pressure detection devices are mounted on the cover, and then heating the heating element through a separate control unit detects the pressure inside the pressure cooker generated by the rise of temperature, and thus the steam discharge device and pressure of the cover. The sensing device performs a predetermined operation to complete the tasteful and nutritious cooking.

In this case, the pressure inside the pressure cooker is very high, and opening the cover in a state in which the pressure is not removed may have a very dangerous result. For example, the contents may quickly pop out due to a difference in temperature and pressure. In particular, opening the cover with excessive internal pressure caused by small children's handling alone may cause internal pressure to be ejected at once, resulting in burn injuries. In such a situation, care should be taken to ensure that opening of the cover is prohibited via a mechanical lock.

However, in the related art, there was no means for locking the cover by a mechanical operation depending on the formation of internal pressure, and the cover was freely opened even when steam was formed, which often led to a dangerous situation. .

That is, only a locking device for controlling the opening and closing degree of the main body and the cover regardless of the formation of the internal pressure is proposed, including the closed end that the cover can be opened despite the excessive internal pressure formation due to the handling hole as described above. do.
