DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation structure of an electronic cooker such as an oven microwave oven.

[0002]

2. Description of the Related Art In a conventional electronic cooker, one function is basically provided for one operation key. Therefore, in the case of a microwave oven having a more complex function, such as a recent microwave oven, the number of operation keys becomes very large, which makes it difficult to use and has a design problem.

[0003]

As a method of solving such a problem, a method of reducing the number of operation keys by integrating menus has been performed. At present, even if aggregation can be performed, a sufficient finished state of cooking cannot be obtained due to differences in various cooking conditions.

The present invention has been made in view of the above problems, and has as its object to reduce the number of operation units by switching the functions of the operation units in a simple configuration.

[0005]

According to the present invention, a door is mounted on an electronic cooking device so as to cover a front opening of the cooking device main body, and a main body side operation section is provided on a front surface of the cooking device main body covered by the door. A door-side operation unit that can be operated by the body-side operation unit is provided at a portion of the door that is opposed to the body-side operation unit, and a function of the body-side operation unit is provided with opening and closing of the door. The switch is provided with a changeover switch for changing over.

[0006]

According to the present invention, the function of the main unit side operation unit is switched with the opening and closing of the door, whereby the operation of the main unit side operation unit when the door is open and the door side operation when the door is closed. Operations of different functions can be performed by each operation of the main body side operation unit through the unit.

[0007]

An embodiment of the present invention will be described.

FIG. 1 shows a state where a door of an oven microwave oven as an electronic cooker of the present invention is closed, and FIG. 2 shows a state where the door is opened.

The microwave oven 1 has a door 4 mounted so as to cover the front opening 3 of the main body 2 of the cooking device. On one side of the front opening 3, as shown in FIG.
A vertically long main body side operation section 6 is formed so as to protrude. The main body side operation unit 6 has a display unit 7 formed at an upper portion, and a plurality of operation keys 8 having operation items displayed on a lower surface thereof. Further, at a position overlapping the main body side operation unit 6 when the door 4 is closed, an operation item different from the display of the main body side operation unit 6 is displayed on the surface, as shown in FIG. An operation unit 10 is formed, and an opening 12 is provided at a position overlapping the display unit 7.

FIG. 5 shows a cross-sectional structure of an overlapping portion of the respective operation units 6 and 10 when the door 4 is closed. The operation unit 10 of the door 4 is attached in a returning direction by a top sheet 13 and a spring 14 therein. When the top sheet 13 is pressed, the corresponding operation key 8 surface is pressed by the tip of the actuator 15. An opposing contact mechanism 18 is provided inside the operation key 8.

Reference numeral 20 denotes a door detection switch as a changeover switch, which is provided as shown in FIG. 6 and switches ON / OFF signals as the door 4 opens and closes. Is switched between when the door 4 is opened and when the door 4 is closed.

That is, when the door 4 is open, the operation is performed with the display contents of the operation keys 8 and FIG. 7 is a matrix diagram showing all the operation item contents at that time. On the other hand, when the door 4 is closed, the operation unit 10
8 is a matrix diagram showing all the operation item contents at that time. In FIG.
Reference numeral 20 denotes various motors, 21 denotes a heater, 22 denotes a high-voltage transformer, and 23 denotes a magnetron.

FIG. 9 shows another embodiment of the operation section 6 on the main body side. The operation section 6 is provided with operation keys capable of changing the heating time after the start of cooking. Then, after the cooking is started, the operating key 8a is pressed and the operating key 8b is pressed, for example, for one minute, so that one additional heating time can be added.
By pressing the operation key 8c and inputting, for example, one minute with the operation key 8b, the heating time can be decremented by one minute, thereby making it possible to adjust the heating time during cooking.

[0014]

According to the present invention, the function of the main body side operation unit is switched with the opening and closing of the door, whereby the operation of the main body side operation unit when the door is open and the door when the door is closed are provided. Since different functions can be operated by each operation of the main body side operation unit through the side operation unit, operation of a capacity twice as large as that of the operation unit can be performed. The quality and design are enhanced.
