Abstract

PURPOSE:To reduce the number of select keys and improve the operability of the titled device by providing the device with an input unit which recognizes hand-writing letters and selects the heating method of a heating chamber and substances to be heated. CONSTITUTION:An operation panel is formed by taking a letter recognizing functions into an operating unit. When a heating time is written by a finger on letter inputting units 5, 6 and a start key (l) is pushed after a manual selection key is pushed, for example, heating is started. According to this method, the function may be selected without providing individual keys and the number of menues may be expanded under neglectng the space for it.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a heating device equipped as an input device with a function of recognizing handwritten characters.

The configuration of the conventional example and its problems Conventional period 1 Te L Flute 1 Prr Yunnato fortune-telling statue
- In the case of 5, selection of heating method and setting of heating time were performed using keys on the operation panel or volume. However, as the number of menus that can be cooked increases, the number of selection keys increases, which not only makes it less user-friendly, but also increases the constraints on the external design due to the increased number of keys, which reduces the appeal of the product. It has become something without.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and by incorporating a character recognition function, it is possible to obtain the effect of reducing the number of selection keys to a large number [1]. In addition, when setting the heating time, instead of the traditional input method using keys or volume control, you can input using letters, making it faster and easier to understand even for inexperienced people. Become. In terms of appearance, it is also possible to create a mold that is highly novel.

Structure of the Invention In order to achieve the above object, the present invention includes a heating chamber and an input section for selecting a heating method for the object to be heated, and the cutting section is equipped with an input device for recognizing handwritten characters. It is.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing the appearance of a conventional microwave oven. 1 is a keyboard for selecting a cooking menu, 2 is a volume for setting the heating time, 3 is a volume for setting the heating temperature, and 4 is a display window for showing the operating status. Explain key human-powered procedures using examples. In the case of the conventional automatic oven microwave oven with a finish sensor shown in the first factor, there is a group of keys called auto keys. This uses a humidity sensor and a temperature sensor to heat and cook the object according to a procedure stored in advance in the memory of a microcomputer, such as reheating rice, oven cooking rolls, kutskii, etc., and cooking gratin etc. Keys are divided by each menu, such as grill cooking. There are over 20 types of auto keys.

Furthermore, in the sale of microwave ovens, there is a tendency to compete on how many menus the models have built-in, and the reality is that if there is space to place the keys, it would be nice to have more selection keys. . However, it is difficult to increase the number of keys not only in terms of space but also in terms of operability. These problems can be solved by incorporating a character recognition function. FIG. 2 is an example of an operation panel in which a character recognition function is incorporated into the operation section. 5 and 6 are character input sections. For example, in the case of reheating cold rice, the user writes the number 1 on the character input section 6 with his or her finger and then presses the start button. In this embodiment, seven frequently used menus are displayed on the operation panel, but if you number and list other menus that are not used frequently in a cookbook etc., the number of menus can be reduced. can be increased up to 99. Next, the manual heating operation will be explained.

In the case of the conventional example shown in FIG. 1, the user first selects one of the four manual selection keys: Alternate High, Alternate Low, Grill, and Oven, and presses the key. Furthermore, set the heating time using volume 2. In the case of FIG. 2 with a character recognition function, after pressing the manual selection key, write the heating time on the character input sections 5 and 6 with your finger. In the case of 50 seconds, write the number 5 in the character input section -5, write the number 0 in the character input section 6, and press the seconds key to distinguish between seconds and minutes. Then press the start key to start heating. Conventionally, a volume was required for time input, but in the embodiment of the present invention, it is also possible to eliminate the volume. Further, in the case of oven cooking, a volume 3 for setting the temperature is also required, but in this case as well, by inputting characters in the same way as inputting the time, the temperature setting volume can also be eliminated.

The character input described above assumes numbers, but this
This is because it is easier to recognize numbers, and once you can distinguish katakana etc., you can use the manual menu selection key and the minute/second °C selection hole. You will be able to appear in space for 1 year.

To give an overview of the character input system, the character input section is divided into 3 x 3 grids, and the number of handwritten input strokes and characteristics of the written characters are compared with pre-installed standard patterns to determine the characters. The structure is as follows.

As described above, this embodiment greatly contributes to the novelty of improving operability and reducing the number of component parts, and can become a groundbreaking innovation as a product.

Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

(1) By assigning numbers to various menus and manually typing the numbers, functions can be selected without the need for individual keys, and the number of menus can be expanded without taking up space. .

(2) The number of menu keys can be reduced, increasing the degree of freedom in design.

(3) Since it can also be used to input time and temperature settings, input devices such as a volume are not required.
