Description

[Detailed Description of the Invention] The present invention relates to an electric cooking device comprising a lower frame for storing electrical components on the lower surface of the main body containing a built-in heating element, a back plate covering the lower frame, and legs.

Conventionally, in this type of electric cooker, as shown in FIG. 5, the back plate 9 of the cooker main body 1 has a structure in which a plurality of legs 13 are screwed to a lower frame 7 made of an electrically insulating material using mounting screws 15. It was a target.

This increases the number of assembly steps, and the deterioration of the material of the lower frame 7 causes poor tightening, resulting in unstable attachment of the back plate 9.

The present invention was developed to eliminate the above drawbacks, and the back plate is attached using legs that are fixed to the cooker body through the lower frame, and the back plate can be attached and detached using one of the legs. To provide a simple and reliable back plate mounting structure that improves workability and prevents poor tightening due to material deterioration of the lower frame.

An embodiment of the present invention will be described below with reference to the drawings.

The structure of the embodiment is as shown in FIGS. 1 to 4, where 1 is the cooking device body, 2 is a heating element, and 3 is a protective frame that is fixed inside the cooking device main body 1, and the heating element is attached to the top of the bottom of the protective frame 3. 2 is installed.

Reference numeral 4 denotes a cooking container which is placed on the heating element 2 inside the cooking device main body 1.

5 is a lid that seals the upper edge of the upper opening of the cooking container 4 with a seal 6.
They are removably engaged so that they are airtightly covered.

Reference numeral 7 denotes a lower frame made of an electrical insulator that comes into contact with the edge of the lower opening of the cooking device main body 1, and is formed to cover the lower opening and house the electrical components 8. The lower frame 7 is provided with a concave portion 12 that is slightly thicker than the thickness of the back plate 9 described below, into which the back plate 9 can be fitted.

The lower frame 7 is in contact with the edge of the lower opening of the cooking device main body 1, and a plurality of leg attachment holes 16 are provided at approximately equal intervals along the periphery of the bottom frame together with the cooking device main body 1.

Reference numeral 9 denotes a back plate, which is a metal plate that covers the electrical component 8 housing portion of the lower frame 7, and the back plate 9 has the same number of legs as the leg attachment holes 16 at the peripheral end thereof, and which are attached to the leg attachment holes 16. A notch 11 formed larger than the notch 13 and a contact surface 17 of the leg 13 described below from the notch 11 in at least one of the notches 11.
A through hole 10 for the protrusion 14 is provided in the vicinity of the notch 11 with an opening having a positional interval slightly larger than the side dimension.

Reference numeral 13 has a plurality of legs, each of which has a protrusion 14 that protrudes toward the abutment surface 17 of the lower frame 7 and the leg 13 that engages with the through hole 10 on the leg 13 that is in contact with the portion having the through hole 10. It was established.

Although the concave portion 12 is provided on the side of the lower frame 7, the concave portion 12 may be provided on the side of the contact surface 17 of the leg 13 even in a structure that holds the back plate 9. There is no change in the fact that the concave surface portion 12 is formed.

The operation of this embodiment will be explained with respect to attachment of the back plate 9.

Flip the lower opening of the cooking device main body 1 upwards, place the lower frame 7 over the lower opening, attach the electrical components 8, fit the back plate 9 into the concave part 12 of the lower frame 7, and then close the back plate. Rotate the through hole 10 of 9 in the counterclockwise direction shown in FIG.
0, and insert the protrusion 14 into the through hole 10 using the leg 13 having the inner protrusion 14 of the plurality of legs 13. It is something that is fixed.

Next, when attaching the other plurality of legs 13, the back plate 9 is fixed together with the legs 13 to the cooking device main body 1 via the lower frame 7.

At this time, in conjunction with the rotational displacement of the back plate 9, the notches 11 also move in the counterclockwise direction as indicated by the arrows, so the plurality of legs 13 move the back plate 9 at the outer periphery of the back plate 9 without the notches 11. It is something that is held and fixed.

Further, among the plurality of legs 13, the other legs 13 without the protrusion 14 can be fixed first, and the back plate 9 can be rotated as described above.
It is then also possible to attach the legs 13 with projections 14.

In this way, the through holes 10 of the back plate 9 and the protrusions 14 of the legs 13 are engaged, and the back plate 9 is adhered and held on the concave portion 12 of the lower frame 7.
And rotation is prevented.

In addition, when removing the back plate 9, the mounting is reversed, and by removing the leg 13 (in this embodiment, one leg) having the protrusion 14, the back plate 9 is rotated clockwise, and the notch 11 is attached to the leg. 1
The back plate 9 can be removed by setting it to the same position as position 3.

According to the present invention, a lower frame equipped with electrical components is attached to the lower opening of the cooker main body, and a plurality of leg attachment holes are provided at approximately equal intervals on the periphery of the lower frame, and a concave portion into which the back plate is fitted. shape, and the peripheral edge of the back plate is formed with notches in the same number as the leg attachment holes, but larger than the legs attached to the leg attachment holes, and at least one notch is formed in the vicinity of the notch. Provide a through hole,
The through hole is placed opposite to the leg attachment hole of the lower frame, and the protrusion provided on the leg is engaged with the through hole to fix the leg to the cooker body via the lower frame. Installation is done with legs that are fixed to the cooker body through the lower frame, and the back plate can be attached and removed using one of the legs of the multiple cylinders, improving assembly work efficiency and preventing poor tightening due to material deterioration of the lower frame. This electric cooker has a simple and reliable mounting structure for the back plate.
