Abstract

PROBLEM TO BE SOLVED: To simplify the resin shape of a lid and to ensure more strength by adding a reinforcing member 9 used for reinforcement in the left and right direction of a product and to protect a projected part in the inside of the lid by surrounding it with each of cutout edge parts of reinforcing plates 8c and 9c and to prevent a reinforcing member 8 used for reinforcement in the back and forth direction of the product from falling down in the outside direction by clamping them together with screws 11. SOLUTION: The reinforcing member 8 used for reinforcement in the back and forth direction of the product and the reinforcing member 9 used for reinforcement in the left and right direction of the product are arranged in the inside of the lid of a pressurizing rice cooker. In accordance with the projected parts in the inside of the lid such as a steam valve and a steam cylinder, horizontal reinforcing plates 8c and 9c are cut out and the surroundings of the projected parts are held by each of the cutout edge parts. A fixing piece 9a of the reinforcing member 9 is laminated on the fixing piece 8b of the reinforcing member 8 and the parts are clamped together with the screws 11.

However, the function of the pressure-type instrument as a lid is improved (light weight and compactness).
Therefore, there is a tendency that the material is made thinner and the thickness of the reinforcing rib is made thinner, so that the reinforcing function may be reduced. As a countermeasure to prevent this, it is conceivable to arrange a reinforcing plate in the front-rear direction of the product, for example, between the hinge pin part on the rear side of the lid and the upper hook on the front side. Is not sufficient. In such a case, in order to secure the strength of the product in the left-right direction, it is necessary to complicate the resin shape in the vicinity thereof.

On the other hand, in recent years, there has been a tendency to increase the cylinder diameter in order to reduce the sound generated when steam is released from a steam cylinder which is a part of the lid, or to maintain the inside of the kettle at a pressure as high as possible. It is in. In these cases as well, it is necessary to increase the strength of the product in the left-right direction of the entire lid, but in reality, distortion and warpage are caused in the left-right direction of the product.
