In particular, the lower cover 92 is installed to cover the automatic steam discharge passage 72 and the upper cover 94 is formed to form a flow space between the lower cover 92 and the lower cover 92. It is installed, the inside of the steam guide guides (96a, 96b) for guiding the flow of steam or rice is formed at the same time the drain hole (92H) is discharged along the steam guide guides (96a, 96b) inside It is formed in, and the storage unit (not shown) for the steam or rice discharged through the drain hole (92H) is collected in one side is detachably installed.

In detail, the lower cover 92 has a hole 92h 'formed at the center thereof, and a flow path through which steam or rice flows is formed in the upper portion of the lower cover 92, and is assembled at one end of the automatic steam discharge passage 82 at one side thereof. A portion (hereinafter referred to as an assembly portion) is formed to protrude more than other portions, and the drainage hole 92H is formed in addition to the assembly portion to induce steam or rice to be naturally discharged, and the assembly portion includes steam or It is preferable that a communication hole 92h is formed so that the rice is ejected, and a separate assembly groove and an assembly protrusion are formed to be assembled at the end of the automatic steam discharge passage 82.

In this case, the lower cover 92 is installed such that the steam discharge passage 72 and the weight 74 pass through the hole 92h ', and the automatic steam discharge passage 82 is assembled to the assembly portion. The lower cover 92 may be directly assembled at the end of the automatic steam discharge passage 82, but may be assembled to a separate sealing member 96 installed at the end of the automatic steam discharge passage 82. More preferably, all of the steam discharged through the steam discharge passage 82 is introduced into the lower cover 92 without leaking.

Next, the upper cover 94 also has a hole 94h 'formed at the same position as the lower cover 92, and a flow path through which steam or rice flows is formed at a lower side thereof, and a part of steam is discharged on the upper surface. At least one vapor discharge hole (94h) is preferably formed to be.

At this time, the upper cover 94 is the lower cover 92 to prevent the steam discharged along the automatic steam discharge passage 82 is discharged directly to the outside through the steam discharge hole (94h) of the upper cover. Although it is preferable to be formed in the position where the steam outlet hole (94h) of the upper cover does not overlap with the assembly portion of the lower cover 92, even if assembled in, the steam outlet hole (94h) of the upper cover is More preferably, it is formed at the position farthest from the assembling portion of 92.

Of course, it is preferable that an assembling protrusion and an assembling groove are formed in each of the upper cover 94 so that the upper cover 94 can be assembled to the lower cover 92. The steam guide guide 96a is formed to protrude upward, and the upper guide 94 has a vapor guide guide 96b downwardly around the hole 94h 'to engage with the vapor guide guide 96a of the lower cover. It is formed to protrude, but may be configured such that the vapor guide guides (96a, 96b) is formed in only one of the cover of the lower cover 92 and the upper cover (94).

As described above, in order to prevent the lower cover 92 and the upper cover 94 from being mounted so as to protrude excessively from the lid 62, a mounting groove 62a is formed in the lid 62. The vapor discharge passage 72 and the automatic steam discharge passage 82 protrude inside the mounting groove 62a, and the lower cover 92 and the upper cover 94 are assembled to the mounting groove 62a. Is installed.

On the other hand, in the mounting groove (62a) even if the steam or rice discharged from the automatic steam discharge passage 82 flows down through the drain hole (92H) of the lower cover so that the drainage of the lower cover can be guided to the storage unit A first auxiliary drainage hole 62h is formed below the hole 92H, and a second auxiliary drainage hole 62h 'is formed so that steam or rice discharged from the steam discharge passage 72 can be directly guided to the storage part. Preferably, the first and second auxiliary drain holes 62h and 62h 'are formed to communicate with the storage part.

Looking at the operation of the first embodiment of the steam discharge device of the electric pressure thermal cooker configured as described above, cooking is made while the rice and water is contained in the inner pot 56, the inner pot 56 and the inner pot lid As the pressure increases in the enclosed space between the 62, steam is generated and flows into the steam discharge passage 72 and the automatic steam discharge passage 82.

In this case, since power is input to the solenoid valve 84, the opening and closing member 86 blocks the automatic steam discharge passage 82 so that steam is not discharged through the automatic steam discharge passage 82.

Of course, if the pressure inside the inner pot 56 is excessively high, the power supplied to the solenoid valve 84 side is cut off so that the opening and closing member 86 opens the automatic steam discharge passage 82 to the automatic steam Steam and rice are discharged through the discharge passage 82, the steam and rice is introduced into the flow path between the lower cover 92 and the upper cover 94 through the communication hole (92h) of the lower cover, A part is directly discharged to the outside through the vapor discharge hole (94h) of the upper cover while the rest is stored in the storage through the drain hole (92H) of the lower cover and the first auxiliary drain hole (62h) of the lid When the user desires, the storage unit may be removed from the body to empty or clean steam or rice.

In addition, when the pressure in the inner pot 56 is greater than the set pressure, the weight 74 is pushed up by the pressure in the inner pot 56 to open the steam discharge passage 72, the inner pot ( 56) The steam and the rice inside flow out along the steam discharge passage 72, and a part of the steam and the rice flow out through the hole 94h 'of the upper cover, and the rest is discharged to the outside of the second auxiliary drain hole 62h of the lid. ') Is collected in the storage unit, the user can remove the storage unit from the main body when desired, to empty or clean the steam or rice.

As such, during cooking, the pressure in the inner pot 56 is increased by controlling the opening and closing of the steam discharge passage 72 and the automatic steam discharge passage 82 by the weight 74 and the solenoid valve 84. It is adjusted to maintain the cooking pressure.

Therefore, since the steam is not directly blown out during cooking, it is possible to prevent a safety accident such as a burn in advance, and to prevent the lid 12 from being contaminated by steam or rice.

Meanwhile, since various heaters are also operated to maintain the temperature inside the inner pot 56 at the temperature maintained while the heat is maintained, the pressure inside the inner pot 56 may be increased, and the solenoid valve 84 in the warm state. Since the power is not supplied to the opening and closing member 86 to maintain the state in which the automatic steam discharge passage 82 is opened, steam is drawn out through the automatic steam discharge passage 82 and inside the inner pot 56. Can keep the pressure constant.

Of course, a part of the steam discharged along the steam discharge passage 72 directly exits to the outside through the steam discharge hole 94h of the upper cover, while the remaining portion of the drain cover 92H and the lid of the lower cover is formed. It is stored in the storage unit through the one secondary drain hole 62h, and when the user desires, the storage unit can be removed from the main body to empty or clean steam or rice.

Therefore, even if the solenoid valve 84 is not opened and closed separately while the heat is being maintained, the internal pressure of the inner pot 56 can be maintained at a constant pressure, thereby reducing periodic operation noise, and separately including a configuration for removing residual pressure. This can improve productivity.

Therefore, steam or rice discharged along the automatic steam discharge passage 82 flows along the flow path between the lower cover 92 and the upper cover 94, and then opens the steam discharge hole 94h of the upper cover. At the same time, the steam is partially discharged to the outside and at the same time, steam or rice is collected in the storage through the drain hole 92H of the lower cover and the first auxiliary discharge hole 62h of the lid.

In addition, steam or rice discharged along the steam discharge passage 72 is blocked by the upper cover 94 and is not ejected to the outside, and all of the storage is performed through the second auxiliary discharge hole 62h 'of the lid. It is gathered in wealth.

As such, when steam or rice is collected in the storage unit, the storage unit may be removed from the main body when the user desires to empty or clean the steam or rice.
