Description

[Detailed Description of the Invention] The present invention relates to a handle device for an electric cooking device such as an electric jar rice cooker or an electric pot, and particularly relates to a mounting structure for a handle cover provided on the top surface of the handle.

The handle of an electric jar rice cooker, typically an electric cooker, has a so-called handle cover that also serves as an accessory that covers a part of the stopper that is installed and fixed in a recess provided in the handle to connect the lid and the main body. It is set up.

Various mounting structures for the above-mentioned handle cover have been proposed in the past, but in this structure, an elongated recess is provided in the longitudinal direction of the upper surface of the handle part, which is integrally formed with the lid part using synthetic resin. A stopper that engages and disengages from a hook provided on the main body is fixed on the front side of the room, and lead wires etc. are stored on the rear side.

Then, the handle cover is fixed by engaging the hook claws provided at the front and rear of the lower surface of the handle cover with the hook recesses provided at the front and rear portions of the recess using the elasticity of the handle cover.

However, as mentioned above, the handle cover is simply fixed by the claws and the recesses at the front and back, so the handle cover made of synthetic resin may deform due to long-term use or suffer from dimensional errors. There was a drawback that the grip between the claw and the recess came loose, causing the handle cover to pop out due to its elasticity.

In addition, since the hooking pawl and the hooking recess are secured at approximately the center of the front and rear parts of the recess, the mounting space for the stopper is small, and its fixation is troublesome, making assembly difficult. It became.

In view of the above-mentioned drawbacks, the present invention is designed to securely attach the handle cover, and to create a minimum amount of hooks, thereby increasing the space for attaching other parts. A frame, 2, is a bottomed cylindrical outer pot that is installed inside the frame 1 with a heat insulating material 3 interposed therein; 4, an annular frame cover that fixes the upper periphery of the frame 1 and the upper periphery of the outer pot 2; 5; is a rice cooking heater provided at the inner bottom of the outer pot 2 and fixed in an exposed state; 6 is an inner pot that can be freely stored in the outer pot 2; 7 is an inner lid that covers the opening of the inner pot 6; 8 is a heat-insulating lid placed on the upper surface of the inner lid 7; 9 is a hinge fixed to the rear outer wall of the frame 1; 1;

Reference numerals 31 and 31 denote a pair of locking protrusions integrally projected from the rear of the handle cover 14, and 32 and 32 denote two positions integrally molded on the lower surface of the handle cover 14 and arranged at a predetermined interval. The regulating pieces 33.33 are hooking claws 3 provided on both sides of the lower surface of the relatively front side of the handle cover 14.
4.34, each of which is offset at a predetermined interval in the front-rear direction, and the position regulating piece 32 on the front side of the position regulating piece is disposed within this predetermined interval. It is positioned.

Reference numerals 35 and 35 indicate guide protrusions provided on both sides of the relatively front lower surface of the handle cover 14, and reference numeral 36 indicates an oblong hole bored between the guide protrusions 35 and 35 of the handle cover.

37 is a back cover that covers the lower part of the frame 1, and 38 is a heat-retaining heater fixed to the upper surface of the heat sink 12.

Next, the order of assembling the handle part and the handle cover will be described. First, the stopper device 23 is fixed to the front side of the recess 15 of the handle part 13.

A pair of fitting projections 29.2 of the handle cover 14

．． 30, the engaging flanges 28, 28 are placed against the stepped portions 16, 16, and the upper part of the handle cover 14 is pressed to fit them together.

The fitting between the fitting projections 29.29 and the fitting grooves 17, 17 is ensured by the tapered portion of the fitting projections 29.29, and is prevented from coming off.

Then, the hooking claws 34.34 of the respective engaging claw pieces 33.33
When engaged with the engaging portion 20.20, the front position regulating piece 3
2 comes into elastic contact with the front reinforcing plate 19, and the rear position regulating piece 32 also comes into elastic contact with the rear reinforcing plate 19, so that the handle cover 14
prevent movement in the front-back direction.

Thereafter, the pair of engagement protrusions 31, 31 are engaged with the engagement steps 22, 22 of the handle portion 13 by utilizing their elasticity.

During the above-mentioned assembly, the operation button 24 is attached to the handle cover 1.

In addition, in the present invention, when assembling the handle part and the handle cover, the fitting protrusion and the fitting groove are provided on the front side, and the engaging protrusion and the locking step are provided on the rear side, but this is because the front and back are reversed. Of course, it is also possible to provide a fitting protrusion on the handle side, a fitting groove on the handle cover side, a retaining protrusion on the handle side, and a locking step on the handle cover side. It is.

As described above, the present invention provides a pair of fitting protrusions in a vertical direction on the inner wall of one side of either a synthetic resin type handle portion that also serves as a lid or a handle cover, and a pair of fitting protrusions on one side of the other side. A mating groove is provided in a substantially vertical direction, a retaining protrusion is provided on the other side of either the handle portion or the handle cover, a locking step is provided on the other side, and a position regulating piece is further provided on the lower surface of the handle cover. A reinforcing plate is provided in the recess, the fitting protrusion is fitted into the fitting groove using the elasticity of the handle cover, the retaining protrusion is engaged with the locking step, and the position regulating piece is Since it is in elastic contact with the reinforcing plate, the - side fitting protrusion and fitting groove fit in the vertical direction, so the force of pushing the end outward due to the elasticity of the handle cover is ensured. In combination with the engagement between the engagement protrusion on the other side and the locking step, the fitting becomes accurate.

Further, as the handle cover is assembled and fixed, the position regulating piece comes into elastic contact with the reinforcing plate, so that there is no movement in the front and back direction, and the reinforcing plate reinforces the recess.

In addition, in the above-mentioned vertical fitting, the handle cover is fitted by simply pushing the handle cover vertically downward from the top, so the fitting is slower than when the handle cover is fitted while tilting from the top to the bottom. It is much simpler and contributes to improving serviceability.
