BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cover for a pressure cooker, and more particularly, to a pressure cooker cover for blocking inflow of microorganisms and harmful bacteria into a pressure cooker.

Generally, non-electric rice cookers and electric rice cookers are used to cook rice. Such a rice cooker is mainly a pressure cooker in which rice is cooked by regulating a constant pressure to a higher pressure, that is, a high temperature.

The pressure cooker generally comprises a general pot and a pressure cover for sealing the pot.

In the pressure rice cooker having the above structure, the lid is provided with a packing and a sealing device for sealing the lid to the pot.

The lid is provided with a pressure regulating valve for discharging the steam when the internal pressure of the pot is raised to a predetermined pressure or higher, to keep the pressure constant.

In addition, a safety device is further provided to prevent the cover from being opened in a state in which the pressure inside the pot is full.

If the pressure cooker is used to cook rice, the internal pressure of the pressure cooker will rise to 130 degrees or more due to the high pressure resistance of the pressure cooker.

When the internal temperature rises above 130 ° C as described above, various bacteria and Escherichia coli which are harmless to the human body and bacteria which cause food poisoning are eradicated.

However, generally after rice is cooked, external air is introduced into the cooker through the safety device. At this time, various harmful bacteria and bacteria are inflowed through the inflow air, and the rice inside the rice cooker is contaminated.

Therefore, when the rice is cooked in a pressure cooker and left in the rice cooker, there is a problem that a person who eats rice due to contamination of various bacteria is exposed to diseases such as food poisoning and diarrhea.

The pressure cooker lid according to the present invention comprises a main body 1, a pressure regulating valve 30, a sealing device 20, a safety device 10, and a packing 50.

The sealing device 20 includes a sealing ring 22 fastened to the outside of the main body 1 and a fastening device 21 provided on the upper side of the main body 1. [

The sealing ring 22 is formed of a pair of semicircular rings. The sealing ring 22 is coupled to the main body 1 such that one side thereof is rotatable using a hinge h.

The fastening device 21 is formed as a pair of left and right, but is not shown in the drawing, but is formed so that tension is maintained inward by a spring.

The fastening device 21 is rotatably coupled to the main body 1 using a hinge pin. At the end of the fastening device 21, a handle for operating the fastening device 21 in the left and right direction is not shown in the drawing, but is provided at one end.

The opposite side of the fastening device 21 without the handle is fastened to the sealing ring 22 so as to be slidable.

When the handle is pressed, the sealing ring 22, which is in close contact with the outer side of the lid by the fastening device 21 elastically supported by the spring in the inward direction, is opened to the left and right.

Therefore, if the pressure cooker lid is placed on the upper side of the rice cooker while holding the handle, and the handle is returned to its original position, the lid is fastened to the upper side of the rice cooker.

At this time, the lid and the rice cooker are sealed by the packing 50 provided inside the sealing ring 22.

A pressure regulating valve (30) for regulating the internal pressure of the rice cooker is provided above the lid. A cover (40) for covering the fastening device (21) is provided on the upper side of the fastening device (21).
