Description

[Detailed description of the invention] This invention is a steam release device for a rice cooker lid that directly communicates the inside of the rice bowl with the outside world to release steam. This invention relates to a device that bypasses and releases steam so that it is not released to the outside together with steam.

As a device of this kind, the applicant of the present application has previously provided a steam release device for a rice bowl lid as shown in FIG. 5′,
It is fixed to a part of the rice bowl lid 3, which is removably locked to the lower surface of the container lid 1 by a locking means such as a lid suspension pin 4, by a joining means such as a rivet or spot welding, and is detoured around the peripheral surface. The lower part of the steam guide tube 5', which is formed to expand and has a ventilation hole 6, faces the lower surface side of the rice bowl lid 3, and the cap 7' for absorbing the sticky substance is removably attached to the lower part of the steam guide tube 5'. It was something I did.

As mentioned above, in the conventional device, since the steam guide tube 5' is fixed to the rice cooker lid 3 by rivets or spot welding, it is not easy to manufacture, and the side wall of the cap 7' is attached to the steam guide tube. 5', the detour ventilation hole 6
The detour vent hole 6 could not be formed sufficiently large, and the detour vent hole 6 would be clogged by the sticky fluid.

The purpose of this invention is to provide a steam venting device for a rice bowl lid that is easy to manufacture and has a sufficiently large detour vent hole 6, which is an improvement on the conventional steam venting device for a rice bowl lid described above. There is.

To explain the embodiment, in FIG. 2, the steam guide tube 5 that is inserted into the peephole 1a of the rice cooker lid 1 is connected to the circumferential edge of the vent 3a of the rice cooker lid 3 on its circumferential surface. In addition to forming a flange 5a for stopping, a threaded portion 5b is formed on the lower peripheral surface of the steam guide tube 5 facing downward from the vent 3a of the rice cooker lid 3, and as shown in FIG. 5. Cut a part of the lower edge vertically to form a ventilation section 5C.

On the other hand, the cap 7 has a lid opening 7a that is sufficiently larger than the ventilation opening 3a of the rice bowl lid 3, and a part of the opening rim is cut out to form a ventilation opening 7b as shown in FIG. A threaded portion 7C that is screwed into the threaded portion 5b of the steam guide tube 5 is formed in the center.

By sandwiching the rice bowl lid 3 and directly integrating the steam guide tube 5 placed on the top side and the cap 7 placed on the bottom side, the steam guide tube 5 and the cap 7 can be attached to the rice bowl lid 3. The ventilation part 7b of the cap 7 and the ventilation part 5 of the steam guide tube 5 are sandwiched together.
C and the steam hole 5d in the upper part of the steam guide tube 5 so that the path that follows the steam hole 5d is a path that detours and guides the steam.

In FIG. 5, a screw 8 is hung from the top of the steam guide tube 5, a cap 7 is screwed onto the screw 8 from the bottom side of the rice cooker lid 3, and the cap 7 is attached to the steam guide tube 5 through the screw 8. This embodiment is indirectly integrated with the cap 7, and is similar to the embodiment shown in FIG. 2 in that a part of the rim of the cap 7 is cut out as shown in FIG. 6 to form a ventilation portion 7b. It is.

In addition to this, the ventilation portion 7b of the cap 7 may be formed by perforating the side wall portion.

In the embodiment shown in FIG. 7, a locking protrusion 9 is used instead of the screw 8 in the embodiment shown in FIG. By fitting into the locking protrusion 9, the cap 7 is indirectly and removably connected to the steam guide cylinder 5.

This device has the above-mentioned structure, and in the case of the embodiment shown in FIG.
, the steam is discharged to the outside through a detour that follows the route of the ventilation section 5C1 of the steam guide tube 5 and the steam hole 5d, so the rice remains in the cap 7 without being blown out of the vessel together with the steam, and the rice is cooked. The first surface of the lid of the jar will not get dirty.

Similarly, in the embodiments shown in FIGS. 5 and 7, the cap 7
Steam is released to the outside through a detour that follows the route of the ventilation section 7b, the steam guide tube 5, and the steam hole 5d.

The rice bowl lid steam release device of this invention is integrated into the rice bowl lid by sandwiching the rice bowl lid and engaging the steam guide tube and the cap, which are formed separately, directly or indirectly. This eliminates the need for troublesome joining methods such as rivets and spot welding, which are required in conventional steam release devices for rice bowl lids, and allows the steam release path to be easily configured during the assembly process, making manufacturing easier. Costs can be significantly reduced.

In addition, in the case of this invention, it is possible to avoid a structure in which the side wall of the cap overlaps with the circumferential surface of the steam guide cylinder.
The vent formed on the side wall of the cap can be made sufficiently large, and the inconvenience seen in conventional steam release devices for rice bowl lids, such as the vent becoming clogged with soot, can be prevented.

In particular, in the case of the embodiment shown in Fig. 2, the steam passing through the ventilation part of the cap is also blocked by the peripheral wall of the flat end of the steam guide cylinder, which has a threaded part, so that the function of preventing the release of slime can be further enhanced. can.
