Description

[Detailed description of the invention] (Field of industrial application) The present invention consists of a pair of lid-side bearing walls formed on a lid that is equipped with electrical components such as a lid heater, such as an electric rice cooker or an electric heat-insulating container, and a main body. A pair of main body side bearing walls formed in the bearing part are hingedly connected by a hinge shaft inserted through them, so that the lid body is pivotally connected to the main body so as to be openable and closable, and the lead wire connected to the electrical component is connected to the main body. The present invention relates to a hinge formed by a hinge shaft formed between a bearing part and a hinge cover passing through a space inside the hinge part.

(Prior Art) This type of gear has the lead wire passing through the space inside the hinge part, so it is more aesthetically pleasing and more flexible than the conventional example in which the lead wire is arranged outside the main body bearing part. This has the advantage that the tube can be omitted and the structure can be simplified.

(Problem to be solved by the invention) However, in the case of this type of jars currently in use, the lead wire is disposed within the space inside the hinge portion without restricting its position. This may obstruct the insertion of the hinge shaft or damage the lead wire when installing the hinge shaft in a predetermined position.

(Means for solving the problem) In order to solve the above problems, the present invention
A pair of lid-side bearing walls formed on a lid body equipped with electrical components such as a lid heater, and a pair of body-side bearing walls formed on a main body bearing part are hinged together by a hinge shaft inserted through them, and the lid body is assembled. An electric rice cooker which is pivotably attached to a main body so as to be openable and closable, and in which a lead wire connected to the electrical component is passed through a space inside the hinge part through which a hinge shaft formed between a main body bearing part and a hinge cover passes through. etc., a lead wire position regulating section is formed on the main body bearing section or the hinge cover to abut on the lead wire immediately below the hinge shaft and regulate the lead wire in a position avoiding the hinge shaft, and the lead wire position regulating section The positional relationship is such that the straight line connecting both the main body bearing and the lead wire outlet to the upper part of the hinge internal space formed just above the hinge axis by the main body bearing and the hinge cover does not pass through the hinge axis. This is a characteristic feature.

(Function) According to the above structure of the present invention, the lead wire outlet and the lead wire position regulating section are located at two points, immediately above and immediately below the hinge axis, to position the lead wire passing through the space inside the hinge section. Since the distance between the position regulation points is relatively close, the part between the two points where the position of the lead wire is regulated is placed on the straight line connecting the lead wire outlet and the lead wire position regulation part. It can be almost restrained. Since this straight line is designed to avoid the hinge shaft or its insertion position, the lead wire portion restrained by the position regulation can be stabilized at a position that avoids the hinge shaft or its insertion position. .

(Effects of the invention) According to the invention, the lead wire outlet and the lead wire position regulating part are located at two points, immediately above and immediately below the hinge axis, to regulate the position of the lead wire passing through the space inside the hinge part. However, since the distance between these position regulation points is relatively close, the part between the two points where the position of the lead wire is regulated is almost constrained on the straight line connecting the lead wire outlet and the lead wire position regulation part. Since this straight line is designed to avoid the hinge shaft or its insertion position, the lead wire portion that is restricted by the position regulation can be stabilized at a position that avoids the hinge shaft or its insertion position. So,
Although the lead wire is installed through the space inside the hinge shaft that the hinge shaft passes through, the position of the hinge shaft may be restricted to a position that avoids the hinge shaft, which may obstruct the insertion of the hinge shaft when attaching the lid later, or prevent the hinge shaft from being inserted. It is possible to prevent the lead wire from being damaged due to insertion of the shaft.
