傷を生ずる危険があつた。 Generally, an electric or gas rice cooker, such as a jar rice cooker, has a frame, an outer pot built into the frame, a bottomed cylindrical inner pot that can be stored inside the outer pot, and an electric heater. Alternatively, it consists of a heat source such as a gas burner, and a lid whose one side is rotatably supported on the frame and the other side is latched, and the high-temperature steam generated during rice cooking is stored in the lid. It is released to the outside air through a steam vent. However, since the steam release part is simply provided at a position that avoids the handle part of the lid body, if the handle is grasped immediately after cooking rice, there is a risk that the arm side will come into contact with the high-temperature steam and cause a burn.

である。 The present invention has been devised in view of the above points, and will be explained below based on the drawings. 1 is a square pot body, 2 is a square frame, 3 is a square cylindrical outer pot built into the frame, 4 is a square cylindrical inner pot that can be freely stored in the outer pot, and 5 is the outer pot. An annular electric heater 6 is provided in an exposed state at the inner bottom of the pot 3, and 6 is a rectangular lid body having a recess 7 on the top surface and a handle 8 spanning the recess and bridging one side and the other side. , one side is rotatably supported on the pot body 1 by a hinge part 9, and the other side is freely latched by a hook 10, and has an upper plate 11 and a lower plate 12 with good heat conduction.
It is composed of. Reference numerals 13 and 13 denote a pair of mounting pins disposed laterally on the lower plate 12 of the lid body 6, 14 an annular packing fixed to the outer peripheral edge of the lower plate 12, and 15 a lid spaced apart from the recess 7 to the outside. The lid body 6 is a steam vent provided on one corner side near the pivot portion side of the body 6 and penetrates the lower plate 12 and the upper plate 11.
The steam generated in the inner pot 4 during rice cooking after the lid is closed is released to the outside air. Reference numeral 16 denotes a frame cover in which the upper peripheral edges of the frame 2 and the outer pot 3 are fitted and fixed, and a continuous dripping groove 17 is formed around the entire circumference of the upper surface, and the groove width at the corner portion is increased. 18 is a rectangular inner lid detachably provided on the lower surface of the lid 6;
A bulging portion 19 is provided with the central portion protruding upward, and a plurality of steam vent holes 20, 20 are provided concentratedly on a part of the upper surface of the bulging portion. 21 is a substantially bell-shaped elastic pressing body fitted into the center of the bulging portion 19;
A thin piece 22 on the upper part and a pressing piece 23 on the lower part are integrally molded. Reference numeral 24 denotes a mounting shaft inserted through the elastic pressing body 21, and a locking plate 25 is provided on the upper part. 26

離れた蒸気抜き部１５より外気中に放出する。 Next, the operation will be described. First, the inner pot 4 and the outer pot 3 are filled with appropriate amounts of rice and water, and the locking receivers 31, 31 of the inner lid 18 are engaged with the mounting pins 13, 13. In this state, the locking plate 25 is pushed upward by the coil spring 30, so the receiving plate 2
6 is pulled upward, so the ring packing 27
is in close contact with the lower surface of the inner lid 18. In addition, when the inner cover 18 is installed, the mounting direction of the inner cover 18 is limited by the mounting pins 13, 13 and the locking receivers 31, 31, so that the steam vent holes 20, 20 are closer to each other than the steam vent part 15. This will be the farthest position. When the lid body 18 is closed, the locking plate 25 of the mounting shaft 24 is pushed up by the lower plate 12, and the dew receiving plate 26 is also pushed down, forming a gap l on the outer periphery between it and the lower surface of the inner lid 18. At the same time, the outer circumferential edge of the inner lid 18 is brought into close contact with the inner pot 4 by the spring 30, and the annular packing 14 comes into elastic contact with the upper outer circumferential edge of the inner pot 4, thereby creating a space between the inner cover 18 and the lower plate 12. form S. When the electric heater 5 is energized and the inner pot 4 is heated, the steam generated from inside the inner pot 4 as the rice cooking progresses flows into the dew receiving plate 26 through the gap 1 and is converted into heavy steam and light steam. The separated and heavy oneba is placed on the dew receiving plate 2.
The light steam stored in the space 6 pushes up the thin piece 22 and flows into the space S through the steam vent holes 20, 20, the flow velocity is weakened in the space, and the light steam separated from the heavier moisture is vented. The steam is released into the outside air from the steam venting section 15 that is farthest from the holes 20, 20.

く火傷を未然に防止できる。 As described above, the present invention includes a pot body consisting of a rectangular frame, an outer pot housed in the frame, and an inner pot housed inside the outer pot, and a recess provided at approximately the center of the top surface. A square lid body having a handle spanning one side and the other side, and a steam release part provided on the lid body to release steam inside the inner pot to the outside when the lid is closed, and a handle of the lid body. One side where one end is located is pivotally supported on the pot body, and the other side where the other end of the handle is located is freely latched, and the steam release part is spaced from the recess and is on a corner part side closer to the pivot part side of the lid body. When opening and closing the lid, your hand naturally fits into the recess, so you don't have to hold both ends of the handle, and you can open and close in a stable manner. can be made thinner and the overall height can be lowered. In addition, because the steam release part was located at the corner of the lid near the pivot part, away from the recess, it was the part that was least likely to be touched by hands, which could cause burns from the high-temperature steam. It disappears. That is, the hand does not protrude outside the recess and does not extend to the pivot side, thereby preventing burns.
