Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steam exhaust device for a lid of a cooking appliance that generates steam from the inside.

Conventionally, as shown in FIG. 1, the lid of a heat-retaining rice cooker has a lower surface member 2 spaced apart below an upper surface member 1, and a steam cylinder 3 having a substantially inverted U-shaped cross section on the lower surface member 2.
was installed, a hole 4 was formed in the upper surface of this steam cylinder 3, the upper part of the steam cylinder 3 was made to face the through hole of the upper surface member 1, and the space between the steam cylinder 3 and the upper surface member 1 was sealed with packing 5. .

This conventional steam exhaust device for the lid has the disadvantage that the steam cylinder 3 is deep drawn and requires troublesome surface machining to form a bead on the side surface, making it easy for cracks to occur during machining. . In addition, if the lower surface member 2 is anodized, the alumite film will crack when the steam cylinder 3 is caulked and fixed, so it is necessary to perform alumite processing after the steam cylinder 3 is caulked and fixed to the lower surface member 2. However, the workability was poor.

The present invention solves the above-mentioned conventional drawbacks, and embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 2, 11 is an upper surface member, and 12 is a lower surface member spaced apart below the upper surface member 11. Corresponding through holes are formed in the upper surface member 11 and the lower surface member 12, and in particular, the peripheral edge of the through hole in the lower surface member 12 projects upward to form a stepped portion 13. Reference numeral 14 denotes a cylindrical body mounted in a through hole of the upper surface member 11, and is made of a flexible material such as silicone rubber. An annular groove 15a is formed on the inner surface of the cylindrical body 14, and a skirt-like tongue portion 15b that comes into elastic contact with the step portion 13 is formed at the lower end.
Reference numeral 16 denotes a steam plate having a substantially inverted U-shaped cross section, and a lower end flange portion thereof fits into a groove 15a of the cylindrical body 14.
17 is a steam hole formed on the upper surface of the steam plate 16.

In the above configuration, the steam generated inside the cooking device is transferred to the through hole of the lower surface member 12, the cylindrical body 14, and the steam plate 16.
The steam is discharged to the outside through the steam hole 17. At this time, since the tongue portion 15b of the cylindrical body 14 is in elastic contact with the step portion 13, steam will not flow into the lid through this gap.

Further, the steam plate 16 does not require deep drawing processing, and cracks do not occur due to processing. Further, since the through holes in the upper surface member 11 and the through holes in the lower surface member 12 are connected by a cylindrical body 14 made of a flexible material, assembly can be easily performed. Further, since the steam plate 16 is not in contact with the lower surface member 12, a high gloss, high hardness plate can be used.

As described above, the lid steam exhaust device of the present invention has a double structure with an upper surface member and a lower surface member, through holes are formed corresponding to the upper surface member and the lower surface member, respectively, and the space between the through holes is made of flexible material. The lower end flange of a steam plate having a substantially inverted U-shaped cross section is fitted into a groove formed on the inner surface of the cylindrical body, and the upper surface of this steam plate has steam holes. , the steam generated inside the cooker can be reliably discharged to the outside without flowing into the double-layered lid, and the steam plate is made of a flexible material and the top The lower end flange is fitted into a groove formed on the inner surface of the cylindrical body to the cylindrical body that connects the through hole of the member and the through hole of the lower surface member. When the lower surface member is anodized, as in the case where the cylinder is caulked and fixed to the lower surface member, cracks in the alumite film do not occur, and the steam plate itself does not require deep drawing, so cracks are caused by processing. Moreover, it has various excellent effects such as being able to be assembled very easily.
