Description

Cooking vessel cover for cooking vessels

The present invention relates to a cover device for a cooking vessel so as not to overflow the steam boiling inside the cooking vessel.

In general, a cooking vessel such as a pot used for boiling and cooking a juicy food is composed of a container body containing a material and a lid covering the container body.

According to the so-called pot cooking vessel, the container body is heated to allow the contents contained in the container body to be heated by moisture, and a lid is prevented to prevent heat loss during heating and to prevent foreign substances from entering the container body. .

On the other hand, in the use of such a conventional cooking pot, if the heating is continued in the lid cover state, the steam pressure in the container body is increased as the water in the container body boils, the phenomenon that the lid is opened by the increased steam pressure This will occur.

In addition, when the lid is opened by the steam pressure, the hot steam is discharged to the outside, which may cause the user to be burned. Also, the heated contents may overflow and extinguish the flame such as the stove, causing the gas to leak. This was also triggered.

In order to solve the problems of the conventional pot-type cooking vessel, a pressure-sensing valve is installed on the lid, so that when the internal steam pressure rises above a certain value, a so-called automatic pressure cooking vessel that lowers the steam pressure by opening the valve has been devised. .

However, in such a prior art, since the pressure-sensitive valve is complicated in construction, there is a risk that the function of the valve may be deteriorated when the valve is used for a long period of time. If the amount of steam generated is greater than the amount of steam discharged through the valve, the pressure inside the cooking vessel also continues to rise, so the problem due to the pressure increase cannot be completely solved.

In addition, there is a problem such that if the steam is continuously discharged, the moisture content of the contents is reduced, so that the concentration of the contents is excessively increased or the contents are pressed into the container.

The present invention has been made to solve the above-mentioned conventional problems, to solve the problem caused by excessive increase in steam pressure by allowing the steam generated from the container body to be intermittently discharged, and the structure is simple, there is no fear of malfunction, discharge It is an object of the present invention to provide a steam recovery cover device for a cooking vessel, by which a part of the steam is recovered to suppress a decrease in moisture of the contents.
