Description

[Detailed description of the invention] The present invention relates to a heating cooker.

In recent years, heating cookers that incorporate electronic circuits to control heating time, etc. have been put into practical use and are attracting attention.

The present invention aims to further improve the performance of a heating cooker equipped with such an electronic circuit, and to make it more convenient and easier to use.

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

FIG. 1 is a perspective view showing a high frequency cooking device to which an embodiment of the present invention is applied. In Figure 1,
A door 2 is provided on the front surface of the main body 1 so as to be openable and closable. Reference numeral 3 denotes an operation panel, which includes a display section 4 and a keyboard 5.

FIG. 2 is a circuit diagram. In FIG. 2, a high voltage transformer 9 is connected to a power fuse 6, a door switch 7 that is linked to the opening and closing of the door 2, and a relay contact 8.
Connect. The high voltage transformer 9 is a capacitor 10,
Connected to magnetron 12 via diode 11. 13 is a control board, to which voltage is supplied by a low voltage transformer 14. A microcomputer 15 is provided on the control board 13 and connected to the keyboard 5 via a converter 16. The converter 16 converts the signal from the keyboard 5 into a signal for the microcomputer 15. The microcomputer 15 displays the contents of this signal on the display section 4. In response to a signal from the keyboard 5, the microcomputer 15 outputs an output signal according to a pre-stored program, and the output signal operates the relay coil 18 via the converter 17 to open and close the relay contacts.

FIG. 3 is a partial external perspective view showing the structure of the operating section and display section. In Figure 3,
An operation panel 3 provided on the front surface of the main body 1 is provided with a keyboard 5 and a display section 4 composed of a fluorescent display tube, a liquid crystal display tube, or the like. The keyboard 5 is provided with a time key 25 for setting heating time, a weight key 26 for setting the weight of the object to be heated, etc., and numeric keys 27 for setting numbers such as time and weight. On the other hand, the display section 4 includes a heating mode display 28 for displaying the type of heating method, and a numeric display 2 for displaying numbers.
9. A display such as a colon 30 for displaying a clock is provided, and a weight unit display 31 for displaying a unit of weight such as g or kg is provided alongside the numeric display 29. Only the necessary portions of each of the seven segments of the numeric display 29 are lit to display the numbers 0 to 9.
According to the heating cooker according to this embodiment, when the heating time is set by operating the time key 25 and the numerical keys 27, the numerical display 2 appears on the display section 4.
The heating time is displayed by 9, and the remaining time is displayed counting down as the heating progresses.
As a result, heating is performed for a certain period of time, and at the same time, the display section can have functions such as minutely advancing time and displaying remaining time. The heating mode display 28 displays the heating method and type selected by the operation panel 22 by lighting.
If a program is stored in the microcomputer 15 in advance for each of the numerical keys 25, by selecting each key, the cooking time, heating output by intermittent heating, etc. can be adjusted automatically according to the pre-stored program. This saves you the trouble of setting each time and allows you to easily heat and cook. Moreover, by setting up the optimum program for the food to be cooked, cooking can always be carried out under the optimum conditions, and the quality of the cooking can also be improved. The display section 4 also displays when performing automatic cooking like this.
The numerical display 29 can also display which menu item is selected. Further, the display section 4 can also display the time by using the numeric display 29 and the colon 30, and can also be used as a clock.

Next, by selecting the weight key 26, the weight unit display 31 is displayed on the display section 24. Next, by pressing the number key 25, a weight input signal is input to the microcomputer 15, and at the same time, the weight is displayed on the display section 24. With this weight of input, the microcomputer 15
By storing the mutual relationship between weight and heating time in advance, it becomes possible to automatically set the heating time and perform heating cooking without having to set the heating time each time.

This significantly reduces the number of operations and effort required compared to looking at a cooking text or a list of cooking times and performing the heating operation according to the instructions. Further, since the heating can be performed for the most suitable heating time depending on the weight of the object to be heated, it is possible to achieve optimal heating. Since the calculation of the heating time is performed by an electronic circuit such as a microcomputer, it is possible to realize an extremely user-friendly heating cooker that requires no effort at all.

As described in this embodiment, the numerical display 29 of the display section 4 shows the time, time, selection key number,
Many different pieces of information, such as weight, will be displayed using the same number, but by providing the weight unit display 31, you can easily distinguish between the weight display and other displays, so you can easily distinguish between the weight display and other displays. It is easy to understand what is being used, and can prevent misreading or misuse. In addition, weight unit display 3
By lighting up 1, it can be visually confirmed that the weight key 26 has been selected, which also prevents erroneous operations and can be expected to provide a sense of security in operations. The input section has input sections for both time and weight information, so time input can be used for heating when the heating time is already known, and when the heating time is unknown but the weight of the object to be heated is known. It is convenient and easy to use because it can be heated by any method, such as by inputting the weight if there is a problem.

Since the weight information is input from an input section provided in the operation section, the structure is extremely simple and inexpensive compared to a structure in which a weight measuring element or a measuring mechanism is provided on a turntable or the like on which the object to be heated is placed. Furthermore, since the measuring mechanism is defective, it is possible to realize a convenient heating cooker that takes up little space and is compact and can be installed anywhere.

Although this embodiment shows an example using the microcomputer 15, it may be selected as appropriate depending on the content of the operation, and if the control is simple, it may be sufficient to configure an electronic circuit using general parts, and the same effect can be achieved. can demonstrate. Furthermore, although the high-frequency heating device has been explained as an example, the effect remains the same even if the heat source changes, such as one using electric heat or one using combustion of gas or the like.

As described above, according to the present invention, with a simple configuration, it is possible to improve the function of the display section, and by extension, to significantly improve the function of the cooking device, thereby realizing a cooking device that is easier to use.
