The elastic member 147 is installed at the second hollow portion 145a of the cap member 145 at the upper portion of the valve 146 so that the valve 146 closes the second hollow portion 145a, 146 in the downward direction. Accordingly, when the pressure due to the steam in the main body 110 reaches a certain high pressure state during cooking, the valve 146 is lifted while compressing the elastic member 147 by the steam pressure, and when the vapor pressure inside the main body 110 drops The valve 146 again closes the second hollow portion 145a by the resilient restoring force of the elastic member 147. [ The first hollow portion 144a of the elevating member 144 has a diameter smaller than the sectional diameter of the elastic member 147 so that the upper portion of the first hollow portion 144a can support the upper end of the elastic member 147, ) Can be smoothly compressed and restored.

The opening and closing ring 148 is formed in a ring shape to be coupled to the outer circumferential surface of the elevating member 144 or the cap member 145. In this embodiment, the opening and closing ring 148 is illustrated as being coupled to the outer circumferential surface of the cap member 145. 5, when the elevation member 144 rises as the internal pressure of the main body 110 rises during cooking, the opening and closing ring 148 is positioned between the outer peripheral surface of the lifting member 144 and the inner peripheral surface of the fixing members 141 and 142 The elevating member 144 is moved downward by the projecting portion 132 of the lid handle 130 as the lid handle 130 is raised at right angles as shown in FIG. And when it is depressed, it opens the inlet portion of the steam discharge path 141c '.

Hereinafter, the operation of the above-configured steam discharging apparatus according to the present invention will be described.

Since the steam pressure is not generated in the main body 110 of the pressure cooking vessel before the cooking is started, the elevation member 144 of the steam discharging means, as shown in FIG. 4, 141 in the lifting and lowering space 141c. Also, since the steam pressure inside the main body 110 is weak even at the beginning of the cooking, the state of FIG. 4 is maintained for a certain period of time. In this case, the lid handle 130 provided on the upper surface of the lid 120 of the pressure cooking container may be folded or erected at right angles, but it is folded as shown in Fig. 1 or Fig. 4 in consideration of cooking desirable.

[ At this time, the opening / closing ring 148 surrounding the periphery of the cap member 145 coupled to the lower side of the elevating member 144 abuts against the bottom surface of the second fixing member 142, And the inlet portion of the steam discharge path 141c 'is closed.

Subsequently, when the steam pressure in the main body 110 of the pressure cooking vessel further rises to reach a constant high pressure, the valve 146 (Fig. 6) installed in the second hollow portion 145a of the cap member 145 ) Rises while compressing the elastic member 147 in the second hollow portion 145a by the high pressure steam pressure to open the lower end of the second hollow portion 145a. The steam inside the main body 110 flows into the second hollow portion 145a of the cap member 145 as shown by the two-dot chain line arrow in Fig. 6 and flows into the second hollow portion 145a from the cap member 145 Through the first hollow portion 144a of the elevating member 144 communicating with the second hollow portion 145a through the gap between the inner circumferential surface of the valve 146 and the outer circumferential surface of the valve 146, .

When the high-pressure steam filled in the main body 110 of the pressure cooking container is discharged to the outside through the steam outlet 144b of the steam discharging means to reduce the pressure, The valve 146 is lowered in the second hollow portion 145a of the cap member 145 by the resilient restoring force of the elastic member 147 as shown in FIG. 5, The lower end of the portion 145a is closed. At this time, residual steam exists inside the main body 110, so that when the lid 120 of the pressure cooking vessel is directly opened, residual high-temperature steam remaining in the main body 110 is diverted to the face portion of the pressure cooking vessel, And the user may be burned.

In order to prevent this, the residual steam inside the main body 110 of the pressure cooking vessel is discharged to the outside as follows. 2 or 7, when the lid handle 130 provided on the lid 120 of the pressure cooking container is held at a right angle by using the hinge shaft 131 while holding the lid handle 130 by hand, The protruding portion 132 provided at a portion facing the mounting portion 121 provided with the vapor discharging means is directed vertically downward to the mounting portion 121 while the protruding portion 132 provided at one side of the vapor discharging means So that the elevating member 144 is pressed downward. 7, the elevation member 144 is lowered by the depth of the protrusion 132 in the elevation space 141c of the first fixing member 141. As shown in FIG. At this time, the steam outlet 144b formed on the upper side of the elevating member 144 enters the elevating space 141c of the first fixing member 141 while the cap member 145 The opening and closing ring 148 surrounding the periphery of the second fixing member 142 is spaced apart from the bottom face of the second fixing member 142. [ Therefore, residual steam inside the main body 110 is discharged to the steam discharge path 141c 'by opening the inlet portion of the steam discharge path 141c' formed between the outer circumferential surface of the elevation member 144 and the inner circumferential surface of the fixing members 141 and 142 .

As described above, according to the steam discharging apparatus of the present invention, the high-temperature, high-pressure steam generated during the cooking of the pressure cooking vessel is discharged to the steam outlet 144b as the valve 146 of the steam discharging means 140 is automatically opened by the steam pressure If the simple operation of setting the lid handle 130 at a right angle is performed before opening the lid 120 immediately after the completion of the cooking, the residual high-temperature steam remaining in the main body 110 of the pressure cooking vessel is discharged into the steam And is discharged in advance through the steam discharge path 141c 'formed separately from the discharge port 144b. Therefore, when the lid 120 of the pressure cooking container is opened immediately after the completion of the cooking, the user of the pressure cooking container can be safely consumed without burning due to high temperature steam.
