Each key arranged on the operation unit 32 is easily operated.

  In the case where the cooked food (object to be heated) stored in the chamber 4 heated by gas or electricity is cooked in an oven, the chamber 4 may be preheated to a predetermined temperature in advance. In that case, the present invention effectively uses this preheating temperature to make the surface layer relatively hard and crisp, such as French bread and cream puffs, so that the inside is softened. Provide a suitable cooker.

  Such baking steps will be described with reference to FIGS. First, with the heating cooker body 1 installed in a predetermined place such as a system kitchen, the power plug is connected to the outlet of the commercial power source 51, the door 2 is opened once, the door switch 52 is closed, and the power circuit 53 Power is supplied, the self-holding circuit 68 operates, the relay contact 69 is closed, and a self-holding state is established.

  In this state, the display circuit 55 operates, and the LEDs corresponding to the automatic cooking key 39 and the manual cooking key 40 are lit, prompting one of them to operate the key. When the manual cooking key 40 is turned on here, the manual menu 33B is selected and set, so that the LED corresponding to the manual menu 33B is lit and prompts the selection operation of the menu below the manual menu 33B. Here, by turning ON the character portion of “oven” in the manual menu 33B (step S1), the oven mode is set.

  In this state, the LEDs corresponding to the temperature up key 42 and the temperature down key 43, which are temperature setting keys, are lit, prompting the temperature setting, and displaying “preheat” on the setting display unit 34. Therefore, by operating the temperature up key 42 and the temperature down key 43, the key input circuit 65 is operated to set an arbitrary preheating temperature (for example, 250 ° C.) (step S2). The set preheating temperature of 250 ° C. (referred to as “preheating setting temperature”) is displayed on the three-digit eight-character display section 34, and this set value is stored in the memory 70. In this state, the LEDs corresponding to the start key 47 and the cancel key 48 are turned on to prompt the key operation. Here, if the cancel key 48 is turned ON, the state before step S1 is restored, but if the operation is continued, the start key 47 is turned ON (step S3), and the solenoid valve drive circuit 60 operates. The solenoid valves 13 and 14 are opened to supply fuel to the gas burner 9, and the igniter drive circuit 61 is operated to cause high-pressure discharge at the ignition electrode 17 to ignite the gas in the gas burner 9. When the start key 47 is turned on, the motor drive circuit 71 is operated to operate (ON) the electric motor 11A of the hot air fan 11 and the electric motor 19 of the cooling fan 20 to enter a preheating start state (step S4).

  By the gas combustion by the gas burner 9 and the operation (ON) of the hot air fan 11, the temperature of the interior 4 rises, and the output value of the interior temperature detection circuit 66 detected by the interior temperature detection sensor 27 is stored in the memory 70. Comparison with the set value of the preheat set temperature (for example, 250 ° C.) is sequentially performed (step S5), and when the temperature in the cabinet 4 reaches such a preheat set temperature, a notification is given by a buzzer, a lamp or the like (step S6). ) Until the door 2 is opened, the gas burner 9 is flashed by opening and closing the solenoid valve 15 by the solenoid valve drive circuit 60 so as to keep the interior 4 at the preheat set temperature. At this time, the electric motor 11A of the hot air fan 11 and the electric motor 19 of the cooling fan 20 are continuously operated (ON) by the motor drive circuit 71. When the door 2 is opened, the combustion of the gas burner 9 is stopped.

  Thus, in the state where the inside 4 is kept at the preheat set temperature, the user once opens the door 2 and then cooks the food on the turntable 6 (or the oven cooking plate placed on the turntable 6). The object to be heated is placed and the door 2 is closed (step S7). As a result, the LEDs corresponding to the time keys 44, 45, and 46 are turned on to prompt time setting, and the LEDs corresponding to the temperature setting keys 42 and 43 are turned on to prompt temperature setting, and the setting display unit 34 The LED corresponding to the “preheat” character is turned off. In this state, the oven cooking timer for setting the oven cooking setting time is set by operating the time keys 44, 45 and 46 (step S8). The set oven cooking set time is displayed on the 3-digit 8-character timer unit 35 and the set value is stored in the memory 70. Then, by operating the temperature up key 42 and the temperature down key 43, the key input circuit 65 is operated, and an arbitrary oven cooking set temperature (also referred to as a heating cooking temperature) lower than the preset preheating set temperature (250 ° C.). ), For example, set to 180 ° C. (step S9). The set oven cooking set temperature (180 ° C.) is displayed on the three-digit eight-character display unit 34, and the set value is stored in the memory 70. The temperature in the interior 4 is high due to the preheating, and the motor 11A of the hot air fan 11 and the motor 19 of the cooling fan 20 are stopped (OFF) by the operation of the motor drive circuit 71.

  In this state, the LEDs corresponding to the start key 47 and the cancel key 48 are turned on to prompt the key operation. Here, if the cancel key 48 is turned on, the state returns to step S6. However, if the operation is continued, the start key 47 is turned on (step S10) and the oven is started. On the other hand, in this oven-started state, the oven cooking set temperature is lower than the preheating temperature, and therefore it is determined that the oven cooking set temperature is lower than the preheating temperature (step S11). 13 and 15 are closed continuously, the gas burner 9 is not combusted, and the motor 11A of the hot air fan 11 is also stopped (OFF) by the operation of the motor drive circuit 71. In this state, the temperature of the interior 4 naturally decreases, but the output value of the interior temperature detection circuit 66 detected by the interior temperature detection sensor 27 and the oven cooking set temperature stored in the memory 70 (180 ° C.) Comparison with the set value is sequentially performed (step S12). Even when the start key 47 is turned on, the set oven cooking timer has not yet started.

  This state is a state where the oven has started but is not waiting for the oven cooking process and is waiting, and the cooked food (heated) on the turntable 6 (or on the oven cooking plate placed on the turntable 6) The surface of the product is baked under the temperature condition of the inside 4 that naturally decreases from the preheating set temperature (250 ° C.). In this state, the temperature of the inside 4 becomes the oven cooking set temperature (180 ° C. above). It continues until it falls, and during that time, the cooked product (to-be-heated product) is in a state of presenting a toasted surface.

  By such a comparison operation, when the temperature of the inside 4 is lowered to the oven cooking set temperature (180 ° C.) (step S12), the oven cooking process is automatically started (step S13). That is, in order to keep the inside 4 at the oven cooking set temperature (180 ° C.), the output value of the inside temperature detection circuit 66 detected by the inside temperature detection sensor 27 and the oven cooking set temperature (stored in the memory 70). Based on the comparison with the set value of 180 ° C.), the heat source unit 10 is operated to open / close the electromagnetic valves 13 and 14 by the electromagnetic valve driving circuit 60 and to control the ignition electrode 17 by the operation of the igniter driving circuit 61. The operation and operation (ON) / stop (OFF) of the motor 11A of the hot air fan 11 and the motor 19 of the cooling fan 20 by the motor drive circuit 71 are performed. At the same time, the set oven cooking timer is started and the countdown operation is started (step S14).

  In this way, the oven cooking process proceeds under the condition of the oven cooking set temperature (180 ° C. above), and cooking on the turntable 6 (or on the oven cooking plate placed on the turntable 6). The inside of the object (object to be heated) is baked. This state is performed for the set time of the oven cooking timer. Then, when the set time of the oven cooking timer ends (step S15), the oven cooking process ends and the heat source unit 10 stops (step S16). That is, the motor 11A of the hot air fan 11 is stopped (OFF) by the operation of the motor drive circuit 71, the electromagnetic valves 13 and 14 are closed by the electromagnetic valve drive circuit 60, and gas combustion in the gas burner 9 is not performed.

  Thus, when the oven is started with the oven cooking set temperature set to a temperature lower than the preheating set temperature after being preheated to the preheat set temperature, the oven cooking is performed until the inside temperature drops to the oven cooking set temperature. It will stand by without shifting to a process, and control operation which shifts to an oven cooking process will be performed based on that the inside temperature fell to oven cooking preset temperature. In addition, based on the fact that the internal temperature has decreased to the oven cooking set temperature, a control operation is performed in which the oven cooking setting timer starts while the process proceeds to the oven cooking process. These operations are achieved by the operation of the control circuit 50 by the microcomputer 54. By such an operation, the surface layer can be baked relatively hard like a French bread or a cream puff, and the inside can be softened. In addition, what is necessary is just to set oven cooking preset temperature and preheating preset temperature according to the kind, magnitude | size, etc. of the cooked food (to-be-heated object) to cook.

  In the above, the preheating set temperature can be set to various temperatures, for example, can be set from 120 ° C. to 300 ° C., and the oven cooking set temperature can also be set to various temperatures, for example, from 120 ° C. to 300 ° C. It can be set. For this reason, what is necessary is just to set to appropriate temperature according to the kind, magnitude | size, quantity, etc. of the cooked food (to-be-heated object).

  As described above, the operation unit 32 of the operation panel 3, that is, the automatic cooking key 39, the manual cooking key 40, the finishing key 41, the time keys 44, 45, 46, the temperature setting keys 42, 43, the start key 47, Since the cancel key 48 and the like are configured so that the corresponding LED emits light and prompts the next operation, the user can easily grasp the correct operation sequence.

  As described above, until the inside temperature is lowered to the oven cooking set temperature, the heating of the inside 4 by the heat source unit 10 is stopped, and in the oven cooking process, the heating of the inside 4 by the heat source unit 10 is started. Do. And the heat source part 10 is equipped with the hot air supply fan 11 which supplies the hot air to the inside 4 of the store | warehouse | chamber, the fan 11 is drive | operated in the preheating process, and the fan 11 stops until the inside temperature falls to oven cooking preset temperature, The fan 11 is operated by the transition to the oven cooking process, and the timer operation for the oven cooking set time starts.

  In the above embodiment, the gas oven is described. Alternatively, when the cooking device according to the present invention is an electric oven, the heat source 10 is an electric heater in a natural convection heating system, and forced convection is performed. The thing of a type heating system is comprised with the fan for hot air which circulates the air heated with this electric heater and this electric heater to 4 in the store | warehouse | chamber. Also in this case, until the inside temperature is reduced to the oven cooking set temperature, the heating of the inside 4 by the heat source unit 10 is stopped, and the heating of the inside 4 by the heat source unit 10 is controlled in the oven cooking process. Like that. When the heat source unit 10 includes a fan for supplying hot air to the inside 4, the fan is operated in the preheating process, and the fan is stopped until the inside temperature is lowered to the oven cooking set temperature. By moving to the process, the fan is operated and the timer operation for the oven cooking set time is started. For this reason, the essence of the invention remains unchanged. In the said Example, although the fan 11 is stopped when the heating by the heat source part 10 is stopped, it is not limited to this, According to a cooking menu or oven cooking preset temperature, the fan 11 is stopped. The rotation speed may be adjusted to continuously rotate, or the fan 11 may be controlled to rotate at a predetermined low speed.
