Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a cooking device such as a microwave oven.

(B) Prior Art Cooking appliances such as microwave ovens are usually provided with an operation panel on the front for setting cooking conditions.
Specifically, the structure of such a panel is
As shown in Publication No. 143203, referring to the electrical component for setting cooking conditions, that is, the volume, the volume is fixed to the rear board, and its operating shaft protrudes forward through an opening in the front board (as described above). Figure 3 of the publication). Alternatively, the volume is fixed to the front board, and its operating shaft projects forward through an opening in the front board (FIG. 4 of the above-mentioned publication). However, in any of the above structures, a film is further attached to the front surface of the front board, and scales for the knobs are marked on the film. The assembly must be done accurately so that there is no misalignment between the knob and the scale on the film, making assembly difficult.

(c) Problems to be solved by the invention It is preferable that the electric component for setting cooking conditions can be easily fixed without causing any misalignment between the knob attached to the operating shaft and the scale.

(d) Means for solving the problem In a cooker equipped with an operation panel for setting cooking conditions, the operation panel is connected to a metal fitting at the ground level and a deformable bending member formed on the metal fitting. a bent portion, a resin frame that covers the metal fitting, and a resin frame that is fixed to the frame with the bent portion sandwiched between the frame and has a diameter slightly smaller than the diameter of the opening of the frame. The present invention is characterized in that it is comprised of an electrical component for setting cooking conditions, in which an operating shaft having a certain size is inserted through the opening, and a knob attached to the operating shaft of the electrical component.

(E) Function: By inserting the operating shaft of the electrical component for setting cooking conditions into an opening with a slightly larger diameter in the frame, it can be easily and accurately fixed without causing any misalignment between the knob and the scale. . The scale is displayed directly on the frame.

(f) Examples The drawing shows a microwave oven according to an embodiment of the present invention.

In FIG. 1, a microwave heating chamber 2 is disposed within a microwave oven main body 1, and a door 3 and a front operation panel 4 for opening and closing the front opening of the heating chamber 2 are provided on the front surface of the main body 1. There is.

FIG. 2 shows the details of such a panel 4, which includes a box-shaped metal fitting 5 at the ground level, a bent part 6 formed into a deformable L-shape on the metal fitting, and the metal fitting 5. and a resin frame 7 covering the bent portion 6, which is fixed to the wall surface of the recess 7a of the frame 7 with the bent portion 6 sandwiched between the resin frame 7 and the recess 7a of the frame 7.
An operating shaft 8a having a diameter slightly smaller than the diameter of the opening 7b in the wall is attached to an electrical component for setting cooking conditions, that is, a time setting volume 8 inserted through the opening 7b, and to the operating shaft 8a of the volume. It consists of a knob 9. A time scale 10 (FIG. 1) is directly marked on the front surface of the frame 7 around the area corresponding to the knob 9.

With such a configuration, the volume 8 is connected to its operating shaft 8.
Since the knob 9 is fixed to the frame 7 with the knob 9 inserted through the opening 7b having a slightly larger diameter, there is no misalignment between the knob 9 attached to the operating shaft 8a and the scale 10 around it. Moreover, fixing in this case is easy. Further, the volume 8 is fixed by sandwiching the bent portion 6 of the metal fitting 5 at the ground level, and is therefore electrically safe.

(g) Effects of the invention According to the invention, the electrical component for setting cooking conditions can be easily fixed without any misalignment between the knob attached to the operating shaft and the scale, and the safety of the electrical component can be improved. You can also increase your cooking time and get a practical cooker.
