Description

DETAILED DESCRIPTION OF THE INVENTION 3 H/Field of Industrial Application The present invention relates to an electric water heater for general household use.

2. Prior Art A conventional sakikiyu θ1; is installed by placing the upper end flange of a bottomed cylindrical container on a spout attached to the upper end of the body, and this spout is attached to the tip of the container. It has a hook fixing part into which the hook part of the lid fits, and a hinge part in the shape of an abbreviation that rotatably supports the lid and is detachable at the rear part.

Problems to be Solved by the Invention In the above-mentioned conventional electric water heater, the hinge part of the spout is shaped like an abbreviation and is detachable, so the lid body is rotatably supported by the hinge part. However, it tends to shift forward relative to the inside of the container, and as a result, the center of the waterproof gasket placed on the intangible bottom surface and the 8g upper end flange do not align, causing the end of the waterproof gasket to touch the lid. There was a problem that when it was closed, it would get stuck inside the vernal equinox, and the seal would become partially weakened.

The lid is still supported by the hinge provided at the rear of the spout, and as the lid closes from its maximum opening angle, the waterproof gasket installed on the bottom of the lid opens. , the rear part of the spout sequentially contacts the upper end flange of the container, and finally the hook part of the lid body is fixed to the hook fixing part of the spout, and then the waterproof gasket is attached for the first time. The entire upper end flange of the container is sealed. In this case, since the hinge of the spout is configured in an L-shape, for example, the waterproof gasket may remain displaced against the upper end flange of the container. If the lid is fixed in that position, the lid will not return to its original position even if the lid is later forced backward, and the upper end flange of the container and the waterproof gasket will remain out of alignment.

Furthermore, if the spout and lid are configured to restrict the position before the hook part of the lid is fixed to the hook fixing part of the spout, the closing force of the lid will be heavy and operability will be poor. It had become. In addition, the difference in appearance between the spout and the lid was large, making it unsightly.

In view of these problems, the present invention aims to prevent the waterproof seal from moving backwards before coming into contact with the upper end flange of the container, in the relationship between the upper end flange of the container and the waterproof gasket disposed on the lower surface of the lid. The object of the present invention is to center the upper end flange of the container and the waterproof gasket on the lid through the spout and the lid.
