Description

[Detailed description of the invention] B. Industrial application field The present invention relates to a steam venting device for a rice cooker in which a steam guide path is formed in the lid body and a spherical valve body is provided in the steam guide path so as to be freely floating. It is something.

B. Prior Art Conventional steam venting devices having a spherical valve body simply place the valve body in the steam guide path to open and close the opening. The disadvantage was that the valve could not be closed, or the valve remained closed due to the valve attached to the valve body, making it impossible to release steam.

○C Purpose of the invention The purpose of the invention is to enable smooth opening and closing of the lower opening of the steam guide path even if a spherical valve body is used in the steam venting device.

○D Structure of the invention The structure of the invention is that a steam guide path is formed in which a spherical valve body is freely disposed on a lid body that closes an opening on the top surface of the rice cooker main body, and the bottom surface of the steam guide path is formed. A support body having an insertion hole bored therein is fitted into the opening, and a recess for receiving the valve body is formed in the upper surface of the insertion hole, and a cutout groove is formed in the recess, and the cutout groove is It is formed at a position spaced apart from the one-bar return hole bored in the outer periphery of the support.

○E Example of the invention 1 is a rice cooker main body, which is composed of an outer frame 2, an inner frame 3, an annular frame body 4 that connects the upper peripheral edges of both, and an internal heat insulating material 5. Inside the container body 1 is a pot 6 for storing food to be cooked.
is detachable. The upper opening of the main body 1 is opened and closed by an outer lid 7, and the upper opening of the pot 6 is opened and closed by an inner lid 8. The outer lid 7 has a top plate 9
and a bottom plate 10, and the outer peripheral edges of both are connected by an annular reinforcing frame 11. A locking pin 12 is suspended from approximately the center of the lower surface of the outer lid 7, and a pressing plate 13 for pressing the inner lid 8 is loosely fitted onto the locking pin 12 via a spring 14. A pressure gasket 15 is provided approximately in the center of the inner lid 8 and is engaged with and disengaged from the locking pin 12, and a steam hole 16 is provided at a suitable location. Further, an annular seal packing 17 is attached between the lower surface plate 10 and the reinforcing frame 11 and comes into contact with the upper peripheral edge of the pot 6. A steam guide path 20 is provided at a suitable location on the outer lid 7.
is formed. The steam guide path 20 includes a cylindrical body 22 having an open bottom surface and a plurality of discharge holes 21 in the top surface, a support body 23 fitted into the bottom opening of the cylindrical body 22, and a freely floating spherical body 22. A valve body 24;
It consists of The support body 23 has an insertion hole 25 formed approximately in the center thereof, a pair of one-bar return holes 27, 27 facing each other in the base 26, and a cylindrical projecting portion 28 having the same curvature as the valve body 24 on the upper surface thereof. A recess 30 having a curved surface is formed. The oneba return hole 27 is opposite to the recess 30,
Notch grooves 31, 31 are placed on a line perpendicular to the line connecting 27.
are formed to face each other.

According to such a configuration, even if the valve body 24 fits into the recess 30 and closes the insertion hole 25 during heat retention or the like, and even if one piece is attached to the surface of the valve body 24, the notch groove 3
At step 1, the one-piece valve escapes, and the valve body 24 is not attracted into the recess 30 by the one-piece valve. Moreover, since the cutout groove 31 through which a large amount of oneba flows out is spaced apart from the oneba return hole 27, the oneba flowing out from the notch groove 31 during rice cooking will not be blown away by the steam spewing out from the oneba return hole 27. .

○F Effect of the invention Since the invention is constructed as described above,
The valve body is not attracted and held in the insertion hole of the support body due to the one-piece stick attached to the valve body, and furthermore, the one-piece valve flowing out from the notch groove is not blown out.
