Abstract

PURPOSE:To increase the number of constitution parts and to decrease the number of constitution parts, by a method wherein an oven frame body, of which an oven consists, is located in a case body, and the liquid crystal displaying device of a control panel is mounted to an openable door located to the opening of the oven. CONSTITUTION:When, during heating cook, with a key board 13 of a control panel depressed, a cooking time and a cooking temperature are set, they are digitally displayed on a liquid crystal displaying device 12 by means of a microcomputer 10a of a printed substrate 10. With the key board 13 of a cooking start controlled, relays 14 and 15 are operated, a magnetron 8 is electrically connected and simultanoeusly, a lamp 7 in a chamber is lighted ON. Meanwhile, when the inside of an oven 2 is observed during heating cooking, depression of the display clear button of the key board 13 results in disappearance of display on the liquid crystal displaying device 12, and this permits an object 5 to be cooked in the oven 2 to be freely observed through a clear openable door 11.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a high frequency cooking device for heating and processing food, and particularly to an operation panel display device in this high frequency heating cooking device.

[Technical background of the invention]

As shown in FIG. 1, a conventional high-frequency heating cooking device includes an open frame body that separates an open space and a machine room into a box-shaped case body (cabinet) a.
The case body a located at the open opening is provided with 11 operating panels C (IHi) that open and close horizontally and are equipped with a display device that displays cooking time, cooking degree, etc.

[Problems with background technology]

However, in the above-mentioned high-frequency heating cooking device, the system components such as the high-voltage transformer, magnetron, and high-voltage capacitor that are incorporated in the machine room are arranged in ample space, and the operation panel C is separated from the space occupied by the machine room. Because of this, it has been difficult to make the width of the case body a too small.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and includes a machine room formed inside the case body by attaching a liquid crystal display of an operation panel to the opening/closing door provided at the open opening of the case body. A high-frequency heating cooking device that aims to reduce the number of component parts by making it smaller, occupying a significantly larger open space, and also using the opening/closing door as a mounting board for a liquid crystal display. It provides:

[Summary of the invention]

The present invention is constructed by providing an oven frame forming an oven inside a case body, providing an opening/closing door at the opening of the oven, and attaching a liquid crystal display of an operation panel to the opening/closing door.

[Embodiments of the invention]

Hereinafter, the present invention will be explained with reference to an illustrated embodiment.

In Figures 2 to 5, reference numeral 1 denotes a box-shaped case body, and inside this case body 1 is an oven 2.
An open frame body 4 is provided which divides and forms one machine room 3, and a shelf board 6 on which food to be cooked 5 is placed is provided inside the oven 2 so as to be freely insertable and removable. Further, on the back plate of the case body 1, there is an interior light 7 for illuminating the oven 2.
The case body 1 forming the machine room 3 is provided with a magnetron 8 with its antenna 8 a protruding toward the oven 2 .

In the machine room 3, electrical parts such as a high voltage transformer and a high voltage capacitor are stored inside the machine room 3 separated by a partition plate 9. The printed circuit board (p.
, c substrate) 10 are provided.

On the other hand, the case body 1 located at the opening of the oven 2 is provided with a transparent opening/closing door n11 that opens and closes in the vertical direction. The constituent liquid crystal display 12 is, for example, W.
h1] It is embedded so that it can display the cooking time, cooking swirl pattern, type of cooking, and its specifications. Further, a keyboard I3 of an operation panel is attached to the opening/closing door 11 below the liquid crystal display 12, and this keyboard 13 has the following functions:
As shown in FIG. 5, it is connected to the microcomputer 10a of the printed circuit board 10. Furthermore, the printed circuit board 1
() is provided with a liquid crystal display tube driver 10b that transmits a signal from the microcomputer 10a to the liquid crystal display 12, and the microcomputer 10a is also provided with a first relay 14.
A second relay 15 is attached, and this first relay 14
teeth.

The power source 17 of the cooling circuit connected to the high voltage transformer 16 can be turned on and off, and the second relay 15 can turn on the interior light 7.

Therefore, in the present invention, when heating and cooking, when the cooking time and cooking temperature are set by pressing the keyboard 13 on the operation panel, the microcomputer on the printed circuit board 10 is controlled by IOa to display the predetermined cooking time and the C1 liquid crystal display 12. In addition to digitally displaying the cooking temperature, by operating the cooking start keyboard 13, both the relays 14 and 15 are activated to pass through the magnetron 8 and turn on the interior light 7. It has become.

On the other hand, when observing the inside of open 2 during cooking,
By pressing the display clear button on the keyboard 13, the display on the liquid crystal display 12 disappears and the transparent opening/closing 111. L
Open 2 through L to cook 5 freely 4+'i
l It is now possible to understand.

〔Effect of the invention〕

As described above, according to the present invention, the open frame body 4 forming the oven 2 is provided inside the case body 1, and the
An opening/closing door If t is provided at the opening of the bunk 2, and this opening/closing door 1
Since the LCD display of the operation panel] 2 is installed in 1,
Not only can the space occupied by the oven 2 be enlarged, but it can also be used as a mounting board for the liquid crystal display 12 on the opening/closing door 11, making it possible to reduce the need for component parts. It has a significant effect, such as being able to perform the following tasks.
