Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric appliance having an electric component on a lid pivotally attached to a main body, and in particular, a lead wire is provided in a hinge portion and the lid is prevented from shaking.

Conventionally, this type of electric appliance, for example, a jar rice cooker, has a power supply section provided on the main body side, and therefore, a rational means for connecting the main body side to the lid side using a lead wire has been required.

Conventional wiring devices of this type include those in which the hinge shaft is hollow and the lead wires are passed through it, and those in which the lid is completely exposed outside near the hinge where the lid is pivotally attached to the main body. There were two types of things that could be placed in the hinge part.

The former is simple in appearance as the lead wires are not visible, but it is difficult to implement unless the shaft of the hinge itself is tightened in the axial direction. Shaking was likely to occur, giving the user a sense of uneasiness during operation.

In the latter case, the above-mentioned backlash can be easily prevented by cutting a thread in a part of the hinge shaft itself and tightening from both sides with screws and nuts, but the lead wire does not look The disadvantages were that the process was visible, the number of parts increased, more materials were required, and there was a high possibility of damage.

The present invention solves the above-mentioned conventional drawbacks, and a jar rice cooker will be described below as an embodiment of the present invention with reference to the accompanying drawings.

In the figure, 1 is a rice cooking heater, and 2 is a protective frame that receives it.

The protective frame 2 is fixed to the upper frame 3 at three locations on the upper flange.

The upper frame 3 is a ring-shaped resin material in which a hook portion and a hinge portion are integrally molded, and a body 4 constituting the outer shell of the main body is fitted therein.

5 is a cord reel, and 6 is a side heater for keeping warm.

Reference numeral 7 denotes an outer lid, which is made of a resin material and includes a handle portion integrally molded therein.

8 is an outer lid cover, which covers the lower side of the outer lid 7.

9 is a hook lever, and 10 is a button, which is a locking mechanism for the entire lid body.

Reference numeral 11 denotes a lid heater, which is attached with double-sided tape to a heat dissipation plate 12 constituting the central lower surface of the lid body.In the center thereof, there is an inner lid mounting shaft 13, and the inner lid 14 is attached to an inner lid holder 15 made of silicone rubber. It can be attached to the lid body through the screws and can be removed without any force.

Reference numeral 16 denotes an inner pot, which is placed in close contact with the top surface of the heater and can be attached to and removed from the main body at will.

To explain the hinge part of the upper frame and outer cover in detail, the hinge part of the upper frame 3 is provided with a through hole 3a for the hinge shaft 17, and at a position as close as possible to this, a through hole 3a is provided for the hinge shaft 17. Groove 3b
is formed, and by attaching the hinge cover 18, the groove portion 3b comes into close contact with the upper surface of the hinge cover 18 to form a through hole.

Therefore, the lead wire 19 is placed in the groove 3b and the hinge cover 18
The lead wire 19 can be fixed in the through hole simply by attaching the lead wire 19.

20 is a lid cover that covers the handle portion of the outer lid 7.

Note that the same effect can be obtained by providing the groove portion 3b on the hinge cover 18 side.

The hinge portion of the outer cover 7 is provided with a through hole 7a for the hinge shaft 17, through which the hinge shaft 17 is passed and fixed with a nut.

Further, in the hinge portion of the outer lid 7, a sector-shaped through groove 7b is provided continuously at a position facing the through hole formed by the groove portion 3b and the hinge cover 18, centering on the through hole 7a. The central angle of the fan shape of the through groove 7b is larger than the rotation angle caused by opening and closing the lid.

Therefore, the lead wire 19 is connected to the upper frame 3 and the groove 3 from the body 4 side.
b and through the through hole formed by the hinge cover 18,
It can be inserted into the outer lid 7 through the through groove 7b of the outer lid γ, and by covering the through groove 7b with the lid cover 20, the processing of the lead wire 19 is not visible from the outside. Separately from the hole, it can be fixed with a screw shaft to prevent the lid from shaking.

In addition, the lead wire 19 is processed through the through groove 7b of the outer cover 7.
Because it only passes through the body, it is easy to assemble, and the body 4
The side hinge portion can be formed integrally with the upper frame since the lead wire 19 does not need to be passed through the through hole.

As is clear from the above description, according to the present invention, the lead wires are not exposed and the hinge shaft is fixed by the screw shaft, so the lid does not shake and is easy to use. The wires can be processed simply by passing them through the through grooves in the lid, making assembly work easier and thus of great industrial value.
