Description

[Detailed description of the invention] The present invention relates to a cooking appliance in which a lid is pivotally supported on a main body.

Recently, many electric cookers of this kind, such as jar rice cookers, have heaters installed inside the lid, but since the power supply is located on the main body, the lid pivots on the main body. It is necessary to process the lead wires at the pivot portion, and models in which the lead wires pass through the hinge portion are increasingly being adopted because they have a better appearance and require fewer parts.

In addition, considering ease of assembly and serviceability, this lead wire processing not only passes the lead wire connecting the lid and main body through the hinge, but also makes sure that the lead wire from the lid and the lead wire from the lid pass through the hinge. , terminals are used to connect lead wires from the main body, and the space is quite large.

It is necessary to process such lead wires to improve ease of assembly, serviceability, etc., and to reduce the number of parts by using as little space as possible.

Conventionally, this lead wire processing has been performed at the hinge portion, and the hinge portion was fixed with screws to the upper frame that constitutes the upper open portion of the main body.

This is to adjust the height of the lid, and for this purpose, space is required to install a hinge fixing base on the upper frame, and a hole is drilled in the body at the bottom position to prevent scratches on the lead wire itself. First, a rubber ring was inserted into the body hole, and a lead wire from the lid was connected through the rubber ring, all of which was covered by the hinge cover.

For this reason, a space to fix the hinge part, a space to join the lead wires, a space to exit the lead wires from the body, etc. is required, which makes the hinge part large, and it is necessary to pass the lead wires from the main body through the holes in the body. There were drawbacks such as requiring scratch-preventing parts and poor workability when removing the body during service.

The present invention solves the above-mentioned conventional drawbacks, and embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a protective frame, which has a substantially cylindrical shape with a bottom, has a heater 2 attached to its bottom, and is screwed to an upper frame 3 at its upper flange.

The upper frame 3 is ring-shaped and constitutes the upper part of the main body, and has a hook receiver 3a that locks the lid 4 and a hinge portion 3b that serves as a fulcrum for opening and closing the lid.

There is a lid heater 5 inside the completed lid 4, and a lead wire 9 is connected from the lead wire 6 through the connection terminals 7 and 8 within the hinge portion 3b.
It is connected to the main body side.

A body 10 constituting the outer shell of the main body is press-fitted and coupled to the upper frame 3, and a back plate 11 covers the lower part and is supported by legs 12.

13 is a cord reel that supplies external current.

In addition, an inner cover 14 that moves in conjunction with the outer cover 4 is attached to a shaft 16 by an inner cover holder 15, and a pot 17 can be freely set inside the main body and is in close contact with the heater 2.
It has a structure that allows you to store food inside.

18 is a hinge shaft that rotatably supports the lid at the hinge portion 3b.

In the above configuration, the lead wire 6 is introduced from the lid heater 5 through the fan-shaped groove 4a formed near the lid 4 facing the hinge portion 3b, and then through the hinge portion 3b. The main body lead wire 9 passes through a recess 3C formed at the upper end of 3b facing the groove 4a and is connected to the connecting terminals 7 and 8.
However, the main body lead wire 9 is guided into the main body side from the through hole 3d formed in the upper frame hinge part 3b above the upper surface position of the body 10 without passing through the body 10, and is connected to the power supply part. ing.

As is clear from the above configuration, according to the present invention, since the hinge part is integrally molded on the upper frame, there is no need for mounting space for the hinge part, and the upper frame itself has a hinge part inside the box shape and inside the main body. Drilling a communicating hole allows for easier body processing and a reduction in the number of parts, and since the lead wires do not penetrate the body, the body can be easily disassembled.
