Description

[Detailed Description of the Invention] The present invention relates to a switching display device used in electric cooking appliances and the like, and particularly aims to provide a switching display device that is easy to distinguish and is inexpensive.

Conventionally, this type of switching display device has a protrusion 22 formed on the outer periphery of an operation knob 21, as shown in FIG.
There was one that matched the scale display 24 of the display board 23, but it had the drawback that it was difficult to distinguish the switching position.

In addition, as shown in FIG.
5 was designed to rotate together with the operating knob 21, but due to assembly variations, the pointer 25 and scale display 24 did not match as shown by the two-dot chain line, resulting in a very unsightly appearance.

The present invention solves the above-mentioned conventional drawbacks, and embodiments of the present invention will be described below with reference to FIGS. 1 to 4.

In Figs. 1 to 4, reference numeral 1 denotes the main body of the electric cooking appliance, and a switching display device is provided on the upper front surface.

This switching display device will be described in detail with reference to FIGS. 2 and 3. Reference numeral 2 represents a rotating shaft, and a slotted portion 2a is formed on the rotating shaft.

Reference numeral 3 denotes an operating knob fitted to the tip of the rotating shaft 2.

4 is a lever fitting member that fits into the slot 2a of the rotating shaft 2;
A rotating plate 5 is fixed, and by rotating the operating knob 3, the rotating plate 5 rotates together with the rotating shaft 2 and the joint member 4.

A portion 5a of the surface of the rotary plate 5 is printed in a different color from the other portions.

Reference numeral 6 denotes a display plate located between the operating knob 3 and the rotary plate 5, and is made of a transparent resin or glass plate.

This display plate 6 is provided with a through hole 7 through which the rotating shaft 2 passes, and a non-see-through portion 8 and a scale display 9 are formed on the back surface by printing or the like, and a plurality of holes are formed at equal distances from the through hole 7. The see-through section 10 is not formed.

Further, the scale display 9 is located near the see-through section 10.

In addition, when the display plate 6 is formed of a metal plate, a scale display 9 may be formed on the surface by printing or the like, and a through hole may be provided near the scale display 9 to serve as a see-through portion 10.

Further, a see-through section 10 is formed at a position corresponding to the different-color print section 5a, and the diameter of the different-color print section 5a is larger than the diameter of the see-through section 10.

In the above configuration, when the operating knob 3 is rotated, the rotating plate 5 rotates integrally via the rotating shaft 2 and the joint member 4.

In this case, the different color printing part 5a is visible through one or more of the plurality of see-through parts 10, and since it matches the position of the scale display 9, the switching position appears clearly.

Furthermore, by making the diameter of the different color printing section 5a larger than the diameter of the transparent section 10, variations during assembly can be absorbed, and the display will not shift even without strict assembly management.

As is clear from the above explanation, the switching display device of the present invention has a different color printed part on the transparent part, so the position of the scale display matches the display part, making it easy to distinguish the switching display, and requires strict assembly management. It is a dog of practical value, as it can be manufactured at low cost because it does not cause any damage.
