Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to the structure of an operation panel for a microwave oven that allows for a wide range of cooking contents with a simple structure.

<Prior Art> The structure of the operation panel in a conventional microwave oven has an external appearance as shown in FIGS. 9 and 10, of which the one shown in FIG. An operation panel 3 is provided on the right side of the operation panel 2, and cooking menu setting keys 4, 4, . The object is the most basic shape.

However, in such a case, the various operation keys are exposed on the surface, so in a kitchen where there is a lot of steam and oil smoke, they can easily get dirty, giving an unsanitary appearance and being a source of failure. It also had the potential to become

Fig. 10 shows an arrangement in which such problems in appearance and other inconveniences are eliminated, and an operation panel ₃₁ is attached to the right side of the door 2 on the front side of the microwave oven body 1, and the right end of the panel 31 is attached to the right side of the door ₂ . A plurality of cooking menu setting keys 4 ₁ , 4 ₁ ... are set in the vertical direction so that they can appear and appear freely, and the setting keys 4 ₁ , 4 ₁ ... are further set so as not to be exposed to the outside and look unsightly. On the front surface of the keys 4 ₁ , 4 _{1 .} . . , a door ₅ that can be opened and closed freely as shown in FIGS. In order to prevent the door 5 from protruding to the front, the door 5 is
Bend the mounting arm 7 and press the setting keys 4 ₁ , 4 ₁ ...
This makes it easy to operate.

As a result, the door 5 may protrude to the side of the microwave oven main body 1 when the door is opened, spoiling the appearance when the door is opened, or when the microwave main body 1 is installed in a cramped space.
If you touch it while doing other cooking tasks, it may get in the way.
In some cases, there was a risk that the door would be damaged due to an unintentionally strong impact.

<Problems to be solved by the invention> The invention solves the problems that the operation panel of the conventional microwave oven occupies a large space during operation, restricts the installation location, and has an unsightly appearance. It is an object of the present invention to provide a setting key that has good operability and allows selection of more types of cooking menus.

<Means for solving the problem> A sliding hidden lid that hides the cooking menu setting key attached to the front of the operation panel, and another cooking menu that is attached to the hidden lid and overlaps and corresponds to the cooking menu setting key. When the setting key, the cooking menu setting key attached to the sliding lid, and the cooking menu setting key attached directly to the operation panel are overlapped, the operation circuit by the cooking menu setting key on the operation panel is activated by the sliding hidden lid. It consists of a switch that can be switched to the operation circuit of the setting key.

<Function> When the menu setting key attached directly to the operation panel and the menu setting key on the sliding hidden cover placed on the outside overlap and correspond, the operating panel is controlled by the sliding hidden cover. The operation circuit of the menu setting key on the top is disconnected and connected to the circuit of the menu setting key on the hidden lid, and it is possible to cook the content corresponding to the setting key on the hidden lid, and the sliding hidden lid can be slid. When the two setting keys no longer overlap, the setting key circuit on the hidden cover is cut off and connected to the setting key circuit on the operation panel by the operation of the changeover switch that is linked to the sliding hidden cover. This makes it possible to select the cooking content, and when not in use, the sliding lid covers all the keys on the operation panel and slides so that only the setting keys on the hidden lid are exposed to the outside.

<Example> Hereinafter, the present invention will be described in detail with reference to an example shown in the drawings.

First, referring to the cases shown in FIGS. 1 to 8, the operation panel 3a attached to the microwave oven body 1 has a plurality of cooking menu setting keys 4a, each corresponding to a type of cooking, on the front surface thereof. 4
The setting keys 4a, 4a, . The switches 14, 14, etc. on the circuit board 15 are designed to make contact with each other, and the panel front section 13 on which the setting keys 4a, 4a,... groups are mounted has a button in the direction in which the setting keys 4a, 4a,... are arranged. Two guide grooves 11, 1 recessed along the
1, insert and fit the inward edges 12, 12 on both sides of the hidden cover 5a that covers the front surface of the rows of setting keys 4a, 4a...
The total length of the guide grooves 11, 11 is approximately twice as long as the longitudinal direction of the hidden lid 5a.
When a is moved over the entire length of the guide grooves 11, 11, the cooking menu setting keys 4a, 4a, . . . covered by the hidden lid 5a are all exposed, as shown in FIG.

In this way, when the hidden cover 5a is lowered, the setting key group A that displays the menu for cooking contents is completely covered, leaving only the heating start key 8, volume 9, and function selection key, making it unsightly. It is possible to eliminate the problem.

Further, as shown in FIG. 4, other cooking menu setting keys 4b, 4b, . and set the corresponding setting key 4.
b, 4b... are configured to overlap and correspond to the setting keys 4a, 4a... when the hidden cover 5b is located at the lowest position along the guide grooves 11, 11 (the state shown in FIG. 4). Moreover, a changeover switch 16 is installed on the operation panel 3a, which can be switched via a lever 17 that is pressed at the lower end when the hidden lid 5b is at the lowest position.
While B presses the lever 17, the changeover switch 16 operates to cut off the circuit of the setting key group A and connect the circuit of the setting key group B (FIG. 6).

Further, when the hidden cover 5b moves upward as shown in FIG. 8, the lever 17 is released from the pressed state (7th
(Fig.), the circuit of the changeover switch 16 is configured so that the setting key group B is cut off and the cooking menu of the setting key group A is operated.

In addition, in the case of the above duplicate setting key method, switch 1
4, 14... shall have a switching operation function corresponding to the key group A and the key group B, respectively, and the switching operation from the key group A to the key group B at once by the switching operation of the changeover switch 16. Switching from key group B to key group A is reversible. Further, reference numeral 18 in the figure indicates a shaft on which the lever 17 is pivotally supported.

As mentioned above, by incorporating many types of cooking menus on one operation panel surface and using the duplicate setting key method like this, it is possible to cook twice as many dishes as there are apparently cooking menus by key operation. It can be pulled out by twisting it, and by doing so, it eliminates the appearance of complication.

<Effects of the invention> The present invention is configured as described above, and when selecting a cooking menu, the hidden setting keys inside can be exposed to the surface by sliding the cover up and down, which is different from the conventional setting keys. Unlike the door type, it does not take up much space and does not spoil the appearance. Also, by using a dual type cooking menu setting key, it is possible to accommodate more cooking items than it appears, and the cooking time is reduced by half. It has many excellent effects, such as being able to hide the items inside, eliminating the apparent complexity, and having a simple and compact structure, while providing the ability to bring out a wide variety of cooking items. This is a highly practical idea.
