Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for an operation button provided on an operation panel of a heating cooker.

Conventionally, the operation buttons provided on the operation panel 3 of this type of heating cooker include an arm 9 protruding from the end of the cooking start button 5 and the output switching button 7, as shown in FIGS. 6 and 7. , 10, 9a, 10a are provided with holes 22, 23 into which the cantilevered fulcrum shaft 21 is inserted. The cooking start button 5 and the output switching button 7 are attached to the operation panel 3 by inserting the fulcrum shaft 21 into the holes 22 and 23 and the hole 14 of the fulcrum bearing 13 protruding inward from the operation panel 3 shown in FIG. Ta. If the operation buttons such as the cooking start button 5 and the output switching button 7 are mounted in this way, the limit is to install two.
If more than one is installed, the fulcrum shaft 21 may become distorted, causing damage to the hole 14 of the fulcrum bearing 13 and the arms 9, 10, 9a, 10a.
In addition to being difficult to insert into the holes 22 and 23, the installation work was also very troublesome.

The present invention includes a main body, a door provided in the opening of a heating chamber provided in the main body so as to be openable and closable, an operation panel provided on the front surface of the main body, and a cantilever fulcrum provided on the operation panel. A plurality of operation buttons each having a shaft, and the operation button is attached to the operation panel by inserting a cantilever fulcrum shaft provided on the operation button into a fulcrum bearing provided on the operation panel, This eliminates the above-mentioned conventional drawbacks.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

Note that the same members as in the conventional example will be described with the same reference numerals.

In FIG. 1, a door 2 is provided at the opening of a heating chamber provided in the main body 1 of the cooking device so as to be openable and closable. 3 is an operation panel provided on the front side of the main body 1, and this operation panel 3 includes a timer knob 4 for setting the cooking time, a cooking indicator light 6 that lights up when the cooking start button 5 is operated, and an output switch button 7 that is turned on when the cooking start button 5 is operated. Each indicator light 8 is provided to turn on.

These operation buttons, the cooking start button 5 and the output switching button 7, are operated by arms 9, 10 and 9a, as shown in FIG.
Cantilevered fulcrum shafts 11, 12 and 11 via 10a
a, 12a are provided. Numeral 13 is a fulcrum bearing provided protruding inside the operation panel 3, and cantilever fulcrum shafts 11, 12, 11a, 12a are inserted into holes 14 provided in this fulcrum bearing 13, respectively, as shown in FIG. And an output switching button 7 where the arm 9 of the cooking start button 5 and the cantilever fulcrum shaft 11 have a dimension m ₂ adjacent to each other.
The distance between the arms 10a is smaller than the dimension _l1 between the arms 10a.

When attaching the output switching button 7 to the operation panel 3, as shown in FIG. Insert and rotate in the direction of arrow A. Next, when attaching the cooking start button 5, push the cantilever shafts 11 and 12 into the hole 14 of the fulcrum bearing 13 in the direction of the arrow B from a position almost perpendicular to the operation panel 3, as shown in FIG. When inserted and rotated in the A direction, the cooking start button 5 and the output switching button 7 can be installed close to each other.

This type of operation button mounting structure is based on the operation panel 3.
The effect can be further enhanced when there is not enough space for mounting and it is desired to mount a large number of operation buttons such as the cooking start button 5 and the output switching button 7 close together.

Further, by configuring the cooking start button 5 and the output switching button 7 in this way, it is easy to attach them to the operation panel 3, so that the installation time can be shortened.

Furthermore, the arm 9 of the cooking start button 5 and the output switching button 7,
10, 9a, 10a and cantilever fulcrum shafts 11, 12, 1
Since 1a and 12a can be integrally molded, the dimensional accuracy of the finished product is also improved.

As is clear from the above description, the heating cooker of the present invention has a cantilevered fulcrum of the operation button from a position substantially perpendicular to the operation panel to the hole of the fulcrum bearing of the operation panel 3, as described in the fourth aspect. If you insert the shaft, you can easily attach it even if there are other operation buttons. In addition, since the attachment and insertion directions of adjacent operation buttons are opposite, when an operation button is operated, even if the operation button tries to come out, the other operation buttons get in the way and it cannot be removed. It is not necessary to use a separate member to prevent it from coming off. In addition, by adopting such an installation configuration, the installation work of the operation button becomes easier, so the installation time can be shortened, and
Since the arm and cantilever fulcrum shaft that make up the operation button can be integrally molded, there is no error in finished dimensions, and this plays an extremely important role in improving productivity. Furthermore, since each operation button has its own fulcrum bearing, the operation button can be pressed with a large force, and a fulcrum shaft configuration of the operation button with a large operating force can be obtained.
