[0001]

The present invention relates to a cooking device such as a microwave oven.

[0002]

2. Description of the Related Art A conventional heating cooking device such as a microwave oven has a function of preheating the inside of a refrigerator with a heating heater. There are no indications of the operation of the display on the display unit. Therefore, the general user cannot easily estimate the time required to reach the preheating set temperature, so that preparation for adding food, preparation after completion of cooking, or other tasks away from the microwave oven can be efficiently performed. Can not do.

[0003]

As described above, in the conventional microwave oven, when the interior of the cooking chamber is preheated by the heater, the cooking time is displayed on the display of the microwave until the preheating set temperature is reached. Is not displayed, the general user cannot efficiently prepare for the completion of cooking or perform other tasks away from the microwave oven, which is extremely inconvenient. In addition, since it is not possible to estimate the time required for heating cooking, it is difficult to know how long before starting the meal to start cooking, and there is a problem that the usability is poor.

[0004] The present invention has been made in view of the problems of the above-described conventional cooking apparatus, and has as its object to provide an easy-to-use cooking apparatus which can easily estimate the time required for cooking. I do.

[0005]

In order to achieve the above object, a cooking device according to the present invention comprises a temperature sensor for detecting a temperature in a cooking chamber having a heating heater, and a temperature sensor for detecting the temperature of the cooking chamber. In a heating and cooking apparatus having a processing circuit for controlling heating based on the above, input means for inputting various information such as a cooking menu and cooking time, and a display unit for displaying various information, a preheating setting is input to the input means. When the preheating setting is made by the input means and the preheating operation by the heating heater is started, the processing circuit changes the current inside temperature of the cooking chamber detected by the temperature sensor and the preheating setting. The preheating temperature arrival time is calculated from the associated preheating set temperature, and the preheating temperature arrival time is displayed on the display unit.

According to this configuration, since the preheating temperature arrival time is displayed on the display unit, the user can know the estimated time required for preheating from the display time on the display unit, and prepare the food in accordance with the time. It is possible to efficiently perform preparation for addition, preparation after completion of cooking, or other tasks away from the microwave oven.

[0007] In addition, by displaying both the preheating temperature arrival time and the current interior temperature simultaneously on the display unit by the processing circuit, the user can also display the current interior temperature in addition to the preheating temperature arrival time. By checking the parts, it is possible to perform other tasks efficiently during preheating with more confidence.

Further, by making the preheating set temperature variable, the preheating set temperature can be changed by the input means. Therefore, the preheating set temperature can be set to an appropriate temperature according to the food and the content of cooking.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an electric block diagram showing an embodiment of the heating cooking device according to the present invention. In this figure, reference numeral 1 denotes a heating and cooking apparatus which is a microwave oven according to the present invention, and power is supplied to the apparatus 1 from an AC power supply 2 such as a commercial AC power supply via a breaker 3. The cooking device 1 includes a cooking chamber 4 having a microwave generator 5 having a magnetron as a heating means and a heating heater 6. Radiant heat from food stored in the cooking chamber 4 is provided. Is cooked by heating with a heater.

Further, the cooking device 4 has a temperature sensor 7 on its inner wall for measuring the temperature in the refrigerator, and the temperature sensor 7 measures the temperature in the cooking chamber 4 during heating of the food. , And generates an electric signal corresponding to the temperature and supplies it to the processing circuit 8. The processing circuit 8 is a circuit for electrically controlling the entire heating and cooking device 3 and is a microcomputer (CP).
U) 8a, a read only memory (ROM) 8b, a random access memory (RAM) 8c, etc., and a DC power supply circuit 9 receiving power from the AC power supply 2 through the breaker 3 It operates by receiving current.

[0011] In particular, when the input means 10 constituted by touch keys or the like is used to input an instruction to display an indication of the time required to reach the preheating, the input contents are stored in the ROM 8b. It stores a program to be displayed on the display unit 11 composed of the above.

Reference numerals 12 and 13 denote switch circuits provided between the microwave generator 5 and the heater 6 of the cooking chamber 4 and the processing circuit 8, and one switch circuit 12 is provided with the breaker. The power supply 3 is connected to the AC power supply 2 via the control circuit 3 and switches whether or not to supply the power from the AC power supply 2 to the microwave generator 5 according to a control signal supplied from the processing circuit 8. Switch circuit 13
Is connected to the AC power supply 2 through the breaker 3 in the same manner as the switch circuit 12, and determines whether to supply the electric power from the AC power supply 2 to the heater 6 in accordance with a control signal supplied from the processing circuit 8.

As shown in this flowchart, after selecting a desired cooking menu (preheating cooking or the like) in advance with the input means 10 and setting the preheating, a start key (not shown) of the input means 10 is operated in step n1. When proceeding to n2, the processing circuit 8 determines whether or not the preheating setting is selected by the input means 10. In this step n2, when the judgment of the processing circuit 8 is negative, that is, when it is judged as No, the processing is ended.

On the other hand, if Yes is determined, the process proceeds to step n3.
Then, it is determined whether the input means 10 has requested the display of the preheating temperature reaching time. In this step n3, when the judgment is No, the processing ends, and when the judgment is Yes, the processing proceeds to step n4, where
The preheating temperature reaching time is calculated from the preheating set temperature set in the OM 8b and the current temperature inside the cooking chamber 4 detected by the temperature sensor 7 in accordance with the program set in the ROM 8b.
