Abstract

PURPOSE:To enable a feeding of data of cooking to be performed with an operation of few keys by a method wherein a setting of a cooking temperature and an output of a heating device is performed in response to the input time caused by one key. CONSTITUTION:During a time in which a depressing of ''TEMP CONTROL'' key 76 is continued, a display at the displaying part 6 is revised by every ''+5 deg.C'' every time 0.5sec is passed. At the time when the desired cooking temperature (for example, 55 deg.C) is displayed at the displaying part 6 and the depressing operation of the key 7 is released, the value displayed at the display part 6 is set at a cooking temperature. Similarly, during the time in which the depressing operation of the ''COOK CONTROL'' key 75, and when a numerical value ''30'' meaning the desired output (for example 30%) is displayed at the display part 6 and if the depressing operation of the key 75 is released, at that time, the numerical value (%) displayed at the display part 6 is outputted and set as an output of the heating unit. With this arrangement, it is possible to set data for heating and cooking the foodstuff with a few key operations.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooking device such as an open range or a microwave oven that automatically cooks food using a microcomputer as a control device.

In recent years, using microcomputers as control devices,
BACKGROUND ART Cooking appliances such as microwave ovens and microwave ovens that automatically heat the food by controlling cooking temperature, heating time, heating device output, etc. to values set by the user have been put into practical use. Conventionally, such cookers have a configuration in which the user sets the cooking pot data by specifying a setting item using keys for specifying different setting items such as cooking temperature, and inputting the setting value using a numeric keypad. It had become.

However, with such a configuration, it is inevitable that the number of key operations will increase, making key operations cumbersome and causing erroneous operations.

For this reason, when setting the heating time, for example, the number of keys corresponding to the number of digits displayed on the numeric display is provided, and the number of the corresponding digit is updated sequentially according to the continuation of the suppression operation of these keys or the number of times they are pressed. When the desired number is displayed, pressing the key is stopped and the number is set.In addition, when setting the cooking temperature and heating device output, after operating the temperature setting or output setting key, the key is pressed as described above. Cooking appliances have been put into practical use that simplify operations and prevent erroneous operations by providing a plurality of numerical setting keys and setting corresponding numerical values by operating each key.

However, although this configuration improves operability when it comes to setting the heating time, the former configuration requires a large number of key operations when setting the cooking temperature and the heating device, while the latter requires a large number of key operations. In this configuration, the setting value is limited to the number of keys.

The present invention has been made in view of the above circumstances, and is based on the VA
To provide a cooker with excellent operability, which allows input of cooking pot data by operating a small number of keys, with a configuration in which setting of I-embedding temperature and heating device output are performed according to the input time using one key respectively. The present invention will be described below based on the drawings showing the embodiments thereof.

As detailed above, the cooking appliance according to the present invention is a cooking appliance equipped with a number fIA display section, a key for setting the cooking temperature, and a key for setting the output of the heating device. This is because the cooking temperature and the output of the heating device are set by causing the numerical display section to sequentially update the setting value of the cooking temperature or the output of the heating device each time the continuous operation or operation is performed. Compared to conventional cooking appliances, the operation panel can be configured with fewer keys, making it easier to operate, reducing the hassle of key operations and reducing the possibility of erroneous operation. By reducing the update interval, it becomes possible to set numerical values as precisely as when using a numeric keypad, thereby simplifying the configuration and operation.

In the above embodiment, the display value is sequentially updated each time a predetermined period of time elapses while the cooking temperature setting key or the heating device output setting key is continuously operated. It is also possible to have a configuration in which the displayed value is updated by one step only, or a configuration in which the displayed value is updated by one step each time a - operation is performed.In these cases, it is possible to prevent operational errors due to missing the timing to release the key operation. becomes possible.
