Description

[Detailed Description of the Invention] The present invention relates to a cooking device, and more particularly, to a wiring structure of a lead wire for feeding power to a lid heater in a cooking device such as an electronic rice cooker.

In conventional electronic rice cooking jars, the lead wire for power supply to the lid heater is generally exposed to the outside from the hinge for opening and closing the outer lid, and then wired by inserting it into the outer lid from the base of the outer lid bundle. Met.

In this case, the power supply lead wire must be covered with a protective tube in order to prevent the power supply lead wire once exposed to the outside from being damaged, or to alleviate twisting and bending of the wire due to opening and closing of the outer cover. Not only is it troublesome to assemble, but it also has the disadvantage of being unsightly.

This invention was made to eliminate the above-mentioned conventional drawbacks,
An insertion passage for the power supply lead wire is formed in the hinge part that connects the main body and the outer cover, and the power supply lead wire is wired inside the outer cover without being exposed to the outside, making assembly easy and improving the appearance. The purpose is to provide cooking utensils that will not cause damage.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings, which are examples of the present invention.

FIG. 1 shows an electronic rice cooking jar which is an example of a cooking device according to the present invention, in which 1 is a main body, 2 is an exterior body, 3 is an outer container, and a heat-retaining heater 4 is attached to the outer surface of the outer container 3. A heating plate 5 and a temperature sensing device 6 are installed on the bottom surface of the outer container 3.

A pot 7 is detachably housed in the outer container 3, and the bottom surface of the pot 7 contacts the top surface of the heating plate 5 to receive heat from the heating plate 5.

Reference numeral 8 denotes an outer lid, which is composed of an outer lid main body 9, a back lid 10, a heat sink 11, and a handle cover 12. A lid heater 13 for heat retention is attached to the back side of the heat sink 11, and the heat sink 11 and the outer lid A heat insulating material 14 is loaded between the main body 9 and the main body 9.

The main body 1 and the outer cover 8 are pivotally connected to each other by a hinge portion 15 attached to the upper end of the main body 1 so as to be freely openable and closable.

As shown in FIG. 2, the hinge portion 15 has a hinge portion body 16
(see FIGS. 3 to 5), a hinge portion cover 25 (see FIGS. 6 and 7), and a dew catcher 29.

The hinge main body 16 has a lead wire insertion passage 17 formed in the form of a recessed groove at its upper end, and bearing holes 19 for a pivot 18 that pivotally supports the outer cover 8 are formed in both upper side walls.

Further, on the back side of the hinge main body 16, a lead wire insertion hole 20 that penetrates the exterior body 2 and opens into the main body 1, a screw insertion hole 21 for fixing the hinge main body 16 to the main body 1, and a dew guide path 22 are provided. Further, the front surface of the hinge main body 16 is provided with a lead wire insertion recess 23 communicating with the lead wire insertion passage 17 and a screw hole 24 for attaching the hinge cover.

The hinge part cover 25 covers the front opening of the hinge part main body 16, and has an insertion hole 27 for a fixing screw 26 (see FIG. 2) formed in the center, and guide ribs 28 on both sides of the lower part. It is being

The dew catcher 29 collects water droplets that drip when the outer lid 8 is opened.
The dew is received through the dew guide path 22 of the hinge main body 16, and the sixth guide rib 28 of the hinge cover 25
It can be attached and detached from the direction perpendicular to the plane of the drawing.

On the other hand, on the hinge portion side of the outer cover main body 9, a long hole 9a that is opened by the rotation angle of the outer cover 8 is provided at a position corresponding to the lead wire insertion passage 17. The lead wire insertion path 17 always corresponds to the elongated hole 9a.

Note that a larger space is formed above the elongated hole 9a of the outer lid main body 9 than in other parts.

The lead wire R for power supply to the lid heater 13 is wired from inside the main body 1 into the outer lid 8 via the lead wire insertion hole 20, the recess 23, the lead wire insertion path 17, and the long hole 9a. .

In the electronic rice cooker having the above configuration, the lead wire R
To explain the wiring method, first, the lead wire R rises from the bottom of the main body 1 along the inside of the exterior body 2 to the attachment part of the hinge part 15, and then passes through the lead wire insertion hole 20 passing through the exterior body 2 to the hinge part main body 16. The length of the outer cover body 9 is guided inward, faces upward inside the recess 23, passes through the hinge body 16 through the lead wire insertion hole 17, bypassing the pivot 18, and is located directly above the lead wire insertion hole 17. Wiring is conducted through the hole 9a into a space provided near the hinge portion of the outer lid 8.

The power supply lead wire R wired in this way connects to the lid heater 13.
At the same time, the hinge part cover 25 is screwed to the front opening of the hinge part main body 16 to prevent the wiring from being exposed to the outside.

When opening and closing the outer cover 8, the lead wire R bends, but since the space near the hinge of the outer cover 8 corresponds to the base of the handle, it forms a larger space than other parts, so the lead wire R bends. It bends in a large arc, so you don't have to worry about it breaking.

As is clear from the above explanation, according to the present invention, the lead wire for power supply to the lid heater is guided from the main body into the hinge part main body,
Since the hinge part is inserted directly into the outer cover from the upper end of the main body, the power supply lead wire is not exposed to the outside.
There is no need to worry about getting injured.

Moreover, since separate members such as a protective tube are not required, the assembly is easy without increasing costs.

In addition, when wiring from the hinge main body to the outer cover, the lead wire is led almost straight from the top of the hinge main body and is wired freely inside the outer cover, so it is easy to open and close the outer cover. The bending of the wire is greatly reduced, and the risk of wire breakage is extremely low, resulting in high safety.
