The catalyst 12 and the exhaust port 1 are disposed on the cooking cabinet 1 side of an exhaust passage (not shown) leading to an exhaust port 14 opened on the
An exhaust fan 16 for forcibly exhausting smoke from the cooking cabinet 1 is provided between them.

FIG. 2 shows an operation section of the cooking menu setting means 6, which includes a display section 6a, an automatic cooking section 6b, a manual cooking section 6c,
It comprises a start switch 6d and a cancel switch 6e. The automatic cooking unit 6b is composed of two automatic menu switches, ie, a full body switch 6aa for baking a whole fish, a fillet / dried switch 6ab for baking a dried or cut fish, and a baking switch 6ac. The fillet / dry switch 6ab is larger than the start switch 6d in the operation section.

The burn control switch 6ac can switch the burn control between three levels of strong, medium and weak according to the user's preference. The manual cooking section 6c includes a 10-minute switch, a timer set switch 6ca of a 1-minute switch, and a heater changeover switch 6cb for switching between double-sided grilling and over-fired grilling.

FIG. 3 shows display examples of the display unit in each state. (A) shows a display state during automatic cooking, (b) shows a display state of remaining time, and (c) shows a display state during smoke removal (exhaust).
FIG. 4 shows a change in the state of each part during cooking during the automatic cooking operation. FIG. 5 shows a flowchart of the microcomputer control after the start of cooking. FIG. 6 shows a change in the detected temperature T of the temperature detecting means when one and four fish are grilled.

Next, the operation of one embodiment of the present invention will be described.

First, the grill 15 is placed on the tray 8 and fish is placed on the grill 15 and inserted into the cooking cabinet 1. Next, the whole body switch 6aa from the automatic cooking section 6b of the cooking menu setting means 6
Then, one of the fillet / dried fish switches 6ab is pressed, and the baking control switch 6ac is pressed according to preference to select between high and low baking. Then start switch 6d
Pressing starts cooking.

The control procedure after the start of cooking will be described with reference to FIGS. When cooking is started, the display section 6a changes to a display state indicating that automatic cooking is being performed. First, the exhaust fan 16 and the catalyst heater 4 are energized.
Is heated, and the air in the cooking cabinet 1 is exhausted by the exhaust fan 16. When a predetermined time t2 (about 30 seconds) elapses in this state, the temperature inside the cooking cabinet 1 is stabilized, and the temperature T detected by the temperature detecting means 5 (normally substantially equal to room temperature) is controlled as the initial temperature T0. It is stored in the microcomputer of the means 7. Note that the detected temperature T is abnormally high even after t2, such as when grilling fish continuously (T2 or more, for example, 80 ° C or more).
In this case, the power is not supplied to the upper heating element 2 and the lower heating element 3 until the detected temperature T falls below the predetermined temperature T2, and the power supply to the exhaust fan 16 is continued, so that the temperature becomes lower than the predetermined temperature T2. The detected temperature T at this time is stored in the microcomputer of the control means 7 as the initial temperature T0.

Subsequently, the lower heating element 3 is energized to generate heat,
Heat the fish and add a moderate amount of brown to the back. As a result, the temperature inside the cooking cabinet 1 rises and reaches the determination temperature T1.
The elapsed time at this time is defined as a detection time t0. Note that the determination temperature T1 is determined by the following determination temperature calculation formula with correction based on the initial temperature T0. Each constant is different for each type of automatic menu.

Automatic Menu Whole Body T1 = A1 + T0 × B1 Automatic Menu Dried / Filled T1 = A2 + T0 × B2 A1, B1, A2, B2: Constant The judgment temperature T1 and the initial temperature T0 are actually determined by the microcomputer of the control means 7. Since the calculation is performed after converting the signal into a signal that can be determined, the signal may be converted into an expression that can be easily processed by the microcomputer and then processed. What is important here is that the determination temperature T1 is determined by a determination temperature calculation formula that differs for each automatic menu, and that the determination temperature T1 is corrected by the initial temperature T0.

When the temperature reaches the determination temperature T1, the lower heating element 3 is turned off, the upper heating element 2 is turned on, and the remaining time t1 is determined by the following remaining time calculation formula corrected by the detection time t0. Each constant is different for each type of automatic menu.

Automatic menu whole body t1 = C1 + t0 × D1 Automatic menu dried fish and fillet t1 = C2 + t0 × D2 C1, D1, C2, D2: constant This time, the surface of the fish is scorched. At this time, in order to obtain a stable baked state with little variation,
It is desirable that the constants D1 and D2 be 3 or less.

This is because if the detection temperature fluctuates due to noise or the like and the detection time t0 fluctuates, the remaining time t1 fluctuates by D1 or D2 times the fluctuation of t0. In order to make this variation as small as possible, it is better to make D1 and D2 as small as possible, and in practice it is better to make it 3 or less.

The remaining time t1 determined by the above calculation is displayed on the display unit 6a, and the displayed remaining time is thereafter subtracted as time passes. The remaining time from this state is 1 / 4t1
Then, the upper heating element 2 is turned off and the lower heating element 3 is turned on. This is to improve the finish so that the meat juice and oil that flow into the back of the fish when the upper heating element 2 is turned on and adhere thereto are baked and do not leave any freshness.

Next, when the time t1 has elapsed and the remaining time display becomes 0, the power supply to the lower heating element 3 is stopped, and a buzzer (not shown) sounds to notify the user of the completion of cooking. As a result, for a fish that emits little smoke, such as a salmon fillet or an open horse mackerel, the exhaust switch 16e is pressed by pressing the cancel switch 6e.
And the power to the catalyst heater 12 is stopped, and the tray 8
, And take out the fish from the grill 15 and eat it.

In the case of a large amount of smoke generated during cooking, such as one-sided saury, the exhaust fan 16 and the catalyst heater 12 are energized for a predetermined time t3 (about 1 minute) to remove smoke after cooking. At this time, the display section 6a is in a display state indicating that smoke is being removed (exhausted). If the user takes out the smoke after removing it, the amount of smoke from the front of the cooking cabinet 1 can be reduced.

In the above operation, when the amount of fish is different,
The larger the amount, the longer it takes for the temperature of the cooking cabinet 1 to rise.
FIG. 6 shows an example of one and four fish. As a result, the detection time t0 for reaching the determination temperature T1 is longer in the case of four fishes than in the case of one fish, so the remaining time t1 is also longer in proportion to t0 according to the remaining time calculation formula. For this reason, when the amount of fish is small, the cooking time is short, and when the amount of fish is large, the cooking time is automatically adjusted so as to be long, and the same degree of burning is obtained.

[0026]

As described above, according to the present invention, the completion of cooking is notified immediately after the power supply to the heating element for cooking is stopped, and the catalyst heater is provided with a time difference from the power supply stop.
The exhaust fan is de-energized, so that food that emits a lot of smoke during cooking, such as saury, can be eaten after exhausting the inside of the cooking cabinet firmly. The ones that emit a small amount of smoke, such as, for example, can be eaten immediately after the power supply to the heating element for cooking is stopped, and the effect is great.
