Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooker, particularly to a lid for a jar rice cooker having a heat-retaining function.

2. Description of the Related Art As shown in FIG. 4, a conventional jar rice cooker has an openable and closable outer lid 2 fixed to the upper opening of a main body 1 by a hinge shaft 3, and operated by a hook lever 4. Fortunately, the outer cover 2 was configured to be opened and closed. The outer lid 2 has a double structure with insulation material 5 to improve the heat retention of the rice.
It is preferable that the inner cover 6' be provided in the inner cover 6' with T-screws 7 in order to insert the heat insulating material 6 into the outer cover 2.

During rice cooking, steam is generated inside the pot 8 placed in the main body 1, and this steam is originally collected in the main body 1 through a steam cylinder or the like.
However, if there is a gap between the upper peripheral edge of the pot 8 and the inner lid 6, steam will leak to the outside from this gap.
This causes defects such as deformation and discoloration of the outer lid 2, which is an external component.

Therefore, to prevent steam from leaking through this gap, a gasket 9 is provided to shield between the top of the pot 8 and the inner lid 6, as shown in FIG. Furthermore, in this sixth prisoner,
10 indicates the flow of steam. However, even with the above configuration, as shown in FIG. gap 1 between
Since 1 is formed as J, it leaks out as shown by the vaporized smell mark 1o. 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 is made of synthetic resin.
Many of them are in the form of a single plate, or have a metal plate t-+7 ring-shaped on the inside that is caulked with rivets, etc., and the inner lid 6 and gasket 9 are attached to this outer lid cover 12. was.

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 expensive.

The present invention solves these problems and aims to provide a cooker lid 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 body, a pot that is removably placed inside the body, and an upper opening of the pot. an inner lid that covers the inner lid, and an outer lid that has an annular lip on the inner surface and covers the upper opening of the main body so as to be openable and closable; A gasket is sandwiched between the pot and the inner lid, and is in contact with the upper periphery of the steel to shield the pot and the inner lid.

According to this structure, the deformation of the outer lid is suppressed by the lip provided on the inner surface of the outer lid, and the gasket that shields the gap between the pot and the inner lid is formed between the outer periphery of the inner lid and the inner surface of the outer lid. Since the outer lid is held in place by the lip provided on the outer lid, 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.

EXAMPLE Hereinafter, an example 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 main body, within which a pot 14 is removably placed, and an upper opening of the main body 13 is covered with an outer lid 15. The outer cover 16 is pivotally attached to the main body 13 by a hinge shaft 16 on the minus side, and is locked on the other side so that the outer cover 16 can be opened and closed by operating a hook lever 17. Further, on the inner surface of the outer lid 16, annular lips 16 to 15 are provided.
b is provided, and on the inner side thereof, there is provided an inner lid fixing boss 150 for fixing the inner lid 18 covering the upper opening of the pot 14 with a screw 20 via a gasket 19.

In the above configuration, during cooking, that is, when the outer lid 16 is closed, the lower part of the gasket 19 contacts the upper periphery of the pot 14 with a bending margin, so that during cooking, steam is generated inside the pot 14. However, the outer cover 15 and the main body 13
The steam will no longer leak through the gap between the steam and the steam, and the steam will be discharged from a predetermined steam port (not shown). In addition, the packing 19 includes two annular lips 151L, 15b and the inner lid 18.
Since the steam is clamped between the outer peripheral part of the steam valve and the outer peripheral part of the steam pipe, steam will not leak through this part, and the steam will be smoothly discharged to a predetermined steam port (not shown). In addition, the deformation of the outer lid 15, which has conventionally been a problem, can be prevented by the annular lips 151L and 15b provided on the inner surface of the outer lid 15 serving as reinforcement. By providing the lips 151L and 15b, the outer cover 1 is even stronger, and has more strength than the conventional outer cover cover.
5 is suppressed, and as a result, the outer lid 15
This eliminates the possibility of steam leakage due to deformation.

Effects of the Invention As described above, according to the present invention, a lip is provided on the inner surface of the outer lid, and between this lip and the outer periphery of the inner lid, there is a lip that comes into contact with the upper periphery of the pot to shield the pot and the inner lid. Because it is configured to hold the gasket between the outer cover and the outer cover, deformation of the outer cover can be completely 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 as in the conventional case, it is easy to assemble and can be obtained at low cost.
