  However, the cooking devices shown in Patent Document 1 and Patent Document 2 are provided with only one heating time display area in the display unit provided in the operation unit when manually cooking, so microwave heating. Despite a cooking device having a plurality of heating means with different heating characteristics such as heating and heater heating, it is not easy to determine which heating means is used for cooking only by the heating time displayed in the heating time display area. There was a problem.

In addition, the cooking device shown in Patent Document 1 or Patent Document 2 is configured with a time key of a similar character string consisting of 10 minutes, 1 minute, and 10 seconds. Is operated, 10 minutes 00 seconds is displayed on the display section, 1 minute is operated when the 1 minute key is operated, and 10 seconds is displayed when the 10 second key is operated.
For this reason, even if the user operates the wrong key, the numbers displayed on the display unit are only 1 and 0, which makes it easy for the operator to misidentify and cause erroneous operations.

  Furthermore, when setting a heating time of less than 10 minutes, such as when cooking with microwave heating, the heating time is set with a time key consisting of 10 minutes, 1 minute, and 10 seconds. When performing, it had to push the 1 minute key 8 times, and there also existed a subject that operation was complicated.

  In addition, when equipped with a plurality of heating means with different heating characteristics, such as microwave heating that has good heating efficiency and can be cooked in a short time, and oven heating that cooks slowly over time, it is necessary to operate each heating means Due to the increase in the number of keys on the operation panel, the key layout becomes complicated, the operability of the keys deteriorates, and the design is impaired. It was.

For this reason, for example, when three time keys are provided on the operation panel, the keys used for setting the time of each heating means are 5 minutes, 1 minute, 10 seconds for microwave heating, and for oven heating. 10 minutes, 5 minutes, 1 minute Even if the keys are optimal, each of the above values or a value that does not make each function difficult to use due to restrictions on the number of keys, for example, 10 minutes You have to set the key by choosing 1 minute, 10 seconds, etc.
In other words, it is difficult to adopt an easy-to-use key arrangement for setting the cooking time of any heating means, and there is a problem that there is a limit in improving the usability of keys.

  In addition, in the case of cooking by switching the heating output such as microwave output, when the heating output is switched, the heating characteristics are different for each heating output, so the heating time cannot be grasped intuitively. There was also a problem that there was a risk of misuse such as incorrect settings.

On the other hand, in the cooking device shown in Patent Document 3, although the heating time can be directly input with the numeric keypad, there is a problem that the operation is complicated because the number of keys is large and it is difficult to find a key to operate.
In addition, since the number of keys on the operation panel increases, there is a problem that the arrangement of the keys becomes complicated and the design is impaired.

In addition, the heating cooker shown in Patent Document 1 includes a plurality of heating means such as microwave heating and heater heating, and combination heating that combines microwave heating and heater heating in the course of cooking. .
However, since only one heating time display area is provided in the display unit, it is impossible to determine which heating means is used for heating time among a plurality of heating means.
For this reason, even if the user uses cooking while looking at the state of the food, it is difficult to determine the progress of heating (cooking progress) simply by looking at the remaining heating time. It was.

  Moreover, although the composite cooking appliance shown in patent document 4 is provided with the several time display area in the display part, this is for displaying the heating time set about each cooking appliance, As for the cooker, there was still a problem that the progress of heating could not be determined only by looking at the remaining heating time.

The present invention solves the above-mentioned problems, and in a cooking device having a plurality of heating means having different heating characteristics, it is easy to use by using an operation panel having a display unit provided with a plurality of heating time display areas. The purpose is to provide a good cooking device.
It is another object of the present invention to provide a heating cooker that sets the heating time and is easy to set the heating time.

A heating cooker according to the present invention includes a heating chamber for cooking food, a plurality of heating means having different heating characteristics, a heating means selection key for selecting a heating means to be used for cooking from a plurality of heating means, The heating time can be entered in different units of time, multiple heating time setting keys that display the units of time that can be entered, and multiple heating time displays that correspond to each of multiple heating means One display section for displaying the heating time input by the heating time setting key in the heating time display area corresponding to the heating means selected by the heating means selection key, and a finish adjustment key for adjusting the heating output If, having an operation unit having a plurality of heating time setting key, in accordance with the heating means selected by the heating unit selection key, the heating time of the input to the heating output of the initial setting Units between are set respectively, when the heating output which is adjusted by the finish adjusting key is smaller than the heating output of the initial setting is in units of larger time than the time unit to the heating output of the initial setting The heating time can be entered .

  According to the present invention, in the cooking device having a plurality of heating means having different heating characteristics on the display unit, the heating time display area is provided for each heating means. Therefore, it is possible to instantly determine which heating means is used for cooking, and to obtain an easy-to-use heating cooker that can prevent erroneous setting.

In addition, since the input value of the time key for setting the heating time is configured to change according to the heating characteristics of the selected heating means, heating by heating means having different heating characteristics such as microwave heating and heater heating is performed. Alternatively, when the heating output is different due to microwave heating, electromagnetic induction heating, or the like, each time key can be set to an optimum time according to the heating characteristics.
That is, it is possible to reduce the complexity of the operation for setting the heating time at the time of cooking, and to obtain an easy-to-use heating cooker that can prevent an erroneous operation due to misrecognition at the time of setting.

  In addition, when guidance is given for keys that can be operated by turning on or blinking LEDs, etc., if a key operation is not accepted for a certain period of time, a guidance display will be displayed for the key that must be operated to move to the next operation step. In addition to increasing the brightness of the display, the guidance display for keys that can be used for other operations is interrupted. Can prompt the user.
