Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cooker, particularly a lid for a jar rice cooker having a heat retention function.

Conventional technology As shown in Fig. 4, the conventional jiya rice cooker has the following features.
The outer cover 2, which can be opened and closed, is fixed to the upper opening of the main body 1 by a hinge shaft 3, and the outer cover 2 is opened and closed by operating it with a lever lever 4. In order to improve the heat retention of the rice, it is desirable that the outer lid 2 has a double structure and has a heat insulating material 5 inside. was fixed with screw 7.

During rice cooking, steam is generated from inside the pot 8 placed inside the main body 1. Originally, this steam is released to the outside of the main body 1 through a steam cylinder, but the upper periphery of the pot 8 If there is a gap between the outer cover 2 and the inner cover 6, steam will leak to the outside through this gap, and this will cause defects such as deformation and discoloration of the outer cover 2, which is an external component.
Therefore, to prevent steam from leaking through this gap,
As shown in FIG. 5, a gasket 9 was provided to shield between the upper part of the pot 8 and the inner lid 6. In addition, in this FIG. 5, 10 indicates the flow of steam. However, even with the above configuration, as shown in FIG. Gap 1 between the upper periphery
1 is formed, and the steam leaks out as shown by arrow 10. For this reason, conventionally, an outer lid cover 12 has been provided to reinforce the outer lid 2 so that it does not deform. This outer lid cover 12
Many of these are in the form of a single plate made of synthetic resin, or have a ring-shaped metal plate crimped inside with rivets, etc., and the inner lid 6 and gasket 9 are attached to this outer lid. It was attached to the cover 12.

Problems to be Solved by the Invention However, in such a conventional configuration, parts such as the outer cover 12 are required to prevent the outer cover 2 from deforming, which increases the number of assembly steps and increases the cost. It was also becoming more expensive.

The present invention solves these problems,
To provide a lid for a cooker that has a simple structure, is less deformed, and does not leak steam.

Means for Solving the Problems In order to solve the above problems, the present invention provides a bottomed cylindrical main body, a pot removably placed inside the main body, and an upper opening of the pot. 22, comprising: an inner lid that covers the main body; and an outer lid that has two annular ribs on the inner surface and that covers the upper opening of the main body so as to be openable and closable;
A gasket is sandwiched between the annular ribs of the book and a rising portion of the outer periphery of the inner lid, which is arranged so as to overlap between the ribs, and which contacts the upper periphery of the pot to shield the pot and the inner lid. It is configured as follows.

Effect According to this configuration, deformation of the outer lid is suppressed by the ribs provided on the inner surface of the outer lid, and the gasket that shields the gap between the pot and the inner lid is connected to the outer periphery of the inner lid and the outer lid. Since the outer lid is held between ribs provided on the inner surface, deformation of the outer lid can be further suppressed, and as a result, a lid for a cooking appliance that does not leak steam can be obtained.

Embodiment Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 3. In the figure, reference numeral 13 denotes a bottomed cylindrical jar rice cooker body. A pot 14 is removably placed inside the body 13, and the upper opening of the body 13 is covered with an outer lid 15. The outer cover 15 is pivotally connected to the main body 13 by a hinge shaft 16 on one side, and is locked on the other side to the outer cover 15 so that it can be opened and closed by operating a lever lever 17. Furthermore, an annular rib 15 is provided on the inner surface of the outer lid 15.
a, 15b are provided, and inside thereof,
Insert the inner lid 18 that covers the upper opening of the pot 14 into the
Inner lid retaining boss 15 fixed with screw 20 via 9
c is provided. Further, an annular rib 15a,
A rising portion is disposed between the inner lid 18 and the outer circumference of the inner lid 18 so as to overlap the ribs 15a and 15b, and holds the gasket 19 between the ribs 15b.

In the above configuration, during cooking, that is, the outer lid 15
When the lid is closed, the lower part of the gasket 19 is in contact with the upper periphery of the pot 14 with a flexible margin. The steam no longer leaks through the gap between the steam and the steam, and the steam is discharged from a predetermined steam port (not shown). Also Patsukin 1
9 is two annular ribs 15a, 15b and an inner lid 1.
8, the steam will not leak from this part and will be smoothly discharged to a predetermined steam port (not shown). Furthermore, the deformation of the outer cover 15, which has been a problem in the past, can be prevented by the annular ribs 15a and 15b provided on the inner surface of the outer cover 15 serving as reinforcement. The provision of the annular ribs 15a and 15b makes the outer cover 15 even stronger, so deformation of the outer cover 15 is suppressed even though the outer cover 15 is stronger than the conventional outer cover cover.As a result, steam leakage due to deformation of the outer cover 15 is suppressed. That will no longer be the case.

Effects of the Invention As described above, according to the present invention, the inner surface of the outer lid has two
An annular rib is provided between the annular rib and a rising portion of the outer periphery of the inner lid arranged so as to overlap between the annular rib and a gasket that abuts against the upper periphery of the pot to shield the pot and the inner lid. Because it is configured to sandwich the outer cover, deformation of the outer cover can be reliably prevented. As a result, steam leakage due to deformation of the outer cover is eliminated. Since it does not require separate parts such as an outer lid cover, it is easy to assemble and can be obtained at low cost.
