Description

[Detailed description of the invention] This invention relates to a menu drum provided on the operation panel of a microwave oven, microwave oven, etc.

Conventionally, the menu drum in a heating cooker is
As shown in Fig. 1, a plate-shaped body a made of aluminum or the like with a cooking menu printed on its surface is bent into a circular or square tube shape, and its joints b at both ends are caulked to form a drum body c. ing. A plurality of protrusions d protrude from both ends of the drum body c...
end plate f with drum shaft e, through hole g of f
It is inserted and fixed in...

However, since the cooking menu is printed in advance on the surface of the plate-shaped body a, cracks h may occur in the printing due to the cutting in the vicinity of the joint part b, and the printed coating may peel off. In addition, a sheet i is attached to the plate-shaped body a to protect the printed surface, but this sheet i is also crimped and peeled off after assembly, but this work is troublesome. Some parts may remain. Furthermore, since there is a caulking process, there are various disadvantages in that it is difficult to obtain the circumferential dimension of the drum body c.

This invention was made by paying attention to the above-mentioned circumstances, and its purpose is to bend a plate-shaped body into a cylindrical shape, provide protrusions at both ends of the jointed portions of both ends,
By engaging this protrusion with the end plate of the drum body, it is possible to provide a menu drum for a heating cooker that eliminates the need for caulking work, is easy to manufacture, prevents cracks on the printed surface, and has high dimensional accuracy. It is something.

This invention will be explained below based on an embodiment shown in the drawings. In FIG. 2, reference numeral 1 denotes a main body of a cooking device such as a microwave oven or an oven range, and an opening/closing door 2 and an operation panel 3 are provided at the front of the main body 1. The operation panel 3 is provided with an opening window 4, and a menu drum 5, which will be described later, is rotatably mounted opposite the opening window 4.

To explain this menu drum 5 in detail, the third
It is constructed as shown in FIG. That is, 6 is a plate-shaped body made of an aluminum material, on the surface of which a large number of cooking menus 7 are printed, and this printed surface is covered with a protective sheet 8. This plate-like body 6 is bent into a circular cylindrical shape so that the cooking menu 7 is on the outside, and its both end joints 9 are bent in the axial direction. moreover,
Projections 10, 10 projecting in the axial direction are provided at both ends, that is, at the top and bottom ends of the joint sections 9, 9, and these projections 10, 10 are connected to a plurality of projections provided in advance at both ends of the plate-shaped body 6. An appropriate distance is maintained between the pieces 11 and 11. End plates 13, 13 are provided at both ends of the drum body 12 configured in this way to close the openings.
is provided. These end plates 13, 13 have a disk shape, and a drum shaft 14,
14 is provided protrudingly. Furthermore, these end plates 1
Engagement holes 15 into which the projections 10 and 10 are inserted and engaged, and through holes 16 into which the projections 11 are inserted and engaged are bored in the peripheries of the projections 3 and 13. Also,
When the plate thickness of the plate-like body 6 is t, the engagement hole 15 has a diameter of 2t.
The engagement hole 15 has an inclined surface 15 on the edge thereof for inserting and guiding the protrusions 10, 10.
a, 15a are formed. Then, the end plates 13, 13 are positioned at both ends of the drum body 12, the protrusions 10, 10 are press-fitted into the engagement holes 15, and the protrusions 11 are inserted into the through-holes 16 and then bent. The main body 12 and the end plates 13, 13 are integrally joined, and the menu drum 5 is completed. At this time, the protrusions 10, 1 of the drum body 12
0 are overlapped and press-fitted into the engagement hole 15, the joining portions 9, 9 are brought into close contact and connected. In addition, after the menu drum 5 is completed, the plate-shaped body 6
When the protective sheet 8 on the surface of the protective sheet 8 is to be peeled off, it can be easily peeled off because there is no caulked portion as in the conventional case.

In the above embodiment, a case was described in which the drum body 12 had a circular cylindrical shape.
This shape may be a polygonal shape, and the mounting state of the menu drum 5 is not limited to the vertical shape, but may be horizontal.

As explained above, this invention involves bending the joints at both ends of a bent plate-like body in the axial direction, providing protrusions at both ends of the joints, and using the protrusions to engage the end plates. Since it is inserted into the hole and engaged, there is no need for caulking at the joints as in the past, which improves manufacturing work, and also eliminates the occurrence of cracks on the printed surface at the caulked areas, resulting in high dimensional accuracy. You can get a menu drum. Furthermore, even when the protective sheet on the surface of the plate-shaped body needs to be peeled off after the menu drum is completed, it can be easily peeled off because there is no caulking part.
