Reference numeral 19 denotes a drive circuit unit that controls the energization of the lower heating element 7. In this embodiment, a triac is used as an element of the fan motor driving means 11, and a relay is used as an element for controlling energization of the upper heating element 6 and the lower heating element 7.
[0012]
In the above configuration, the operation according to the present embodiment will be described with reference to FIG. 3. FIG. 3 shows an example of the cooking time set by the cooking time setting means 14 and the energization pattern to the upper heating element 6 and the lower heating element 7. In the figure, the horizontal axis indicates the elapsed time since the start of cooking, the vertical axis indicates the energization state of the upper heating element 6 and the lower heating element 7, (a) is the set time of 16 minutes, (b) is the set time. Is 17 minutes, (c) is a set time of 18 minutes, and (d) is a set time of 19 minutes.
[0013]
The upper heating element 6 and the lower heating element 7 are alternately energized to be able to use a heater with a higher heating power than when energized at the same time. The time is 2 minutes.
[0014]
In each of the cases (a), (b), (c), and (d), alternate energization is performed every 2 minutes until 12 minutes have passed since the start of cooking, and then the remaining time is 4 minutes ( In the case of a), the upper heating element 6 and the lower heating element 7 are each 2 minutes, the remaining time is 5 minutes (b), each 2 minutes 30 seconds, and the remaining time is 6 minutes (c), the upper and lower heating elements When the remaining time is 1 minute and the remaining time is 7 minutes (d), the upper and lower heating elements are energized for 2 minutes, respectively, and then each 1 minute and 30 seconds are energized to finish cooking.
[0015]
As a result, the energization time for each heating element is 8 minutes each for (a), 8 minutes 30 seconds for (b), 9 minutes for (c), and 9 minutes 30 for (d). Second, the ratio of the energization time to the upper heating element 6 and the lower heating element 7 can be made constant at 50%.
[0016]
As a result, since the energization time is controlled so that the ratio of the energization time to the upper heating element 6 and the lower heating element 7 becomes constant according to the set time, the degree of baking on the upper and lower surfaces of the object to be cooked is made constant. It is something that can be done.
[0017]
In this embodiment, the energization ratios of the upper heating element 6 and the lower heating element 7 are made the same, but the temperature distribution in the cooking chamber 3 such as the distance from the heating element to the mounting table 5 and the flow of air, etc. In addition, the same effect can be obtained by setting the energization ratio of the upper heating element 6 and the lower heating element 7 together. In the present embodiment, energization is started from the upper heating element 6 at the start of cooking, but the same effect can be obtained even when energization is started from the lower heating element 7.

[0019]
FIG. 4 is a diagram showing an example of the cooking time set by the cooking time setting means 14 and the energization pattern to the upper heating element 6 and the lower heating element 7, the elapsed time from the start of cooking on the horizontal axis, the vertical axis The energized state of the upper heating element 6 and the lower heating element 7 is shown in FIG. When the user sets the cooking time (16 minutes in this reference example) and starts cooking, in (a), the upper heating element 6 is first energized for 2 minutes, and then the lower heating element 7 and the upper heating element 6 are set to 2 Energize every minute and finally energize the lower heating element 7 for 2 minutes to finish cooking. In (b), the lower heating element 7 is first energized for 2 minutes, then the upper heating element 6 and the lower heating element 7 are energized every 2 minutes, and finally the upper heating element 6 is energized for 2 minutes to finish cooking.
[0020]
In this way, at the start of cooking and immediately before the end of cooking, the heating elements that are different from each other are energized to finish cooking. As a result, the energization time for each heating element is 8 minutes and 30 seconds in the case of (a), and 9 minutes and 30 seconds in the case of (b). The ratio of the energization time to the upper heating element 6 and the lower heating element 7 Can be kept constant at 50%.
[0021]
As a result, when cooking the same food to be cooked continuously, only one heating element is energized for a long time to prevent heating only one side of the food to be cooked, and the top and bottom baking conditions are the same. Can do.
[0022]
(Reference Example 2)
Next, Reference Example 2 will be described with reference to FIG. In addition, the thing of the same structure as the said Example attaches | subjects the same code | symbol, and abbreviate | omits description.
[0023]
FIG. 5 is a diagram showing an example of cooking time when the cooking time is changed by the cooking time setting means 14 during cooking, and an energization pattern to the upper heating element 6 and the lower heating element 7. The elapsed time and the vertical axis indicate the energized state of the upper heating element 6 and the lower heating element 7. Moreover, (a) is a case where the cooking time is changed during energization to a heating element different from the heating element energized at the start of cooking (lower heating element 7 in this embodiment), and (b) is energized at the start of cooking. The state when the cooking time is changed during energization of the same heating element as the heating element (the upper heating element 6 in this reference example) is shown.
[0024]
When the user sets the cooking time (16 minutes in this embodiment) and starts cooking, cooking starts with the heating pattern shown in FIG. 3 minutes have passed since the start of cooking (arrow part), and the cooking time setting means 14 is operated while the lower heating element 7 is energized to newly set the cooking time to 17 minutes (14 minutes from the setting change to the end). When set, the control means 15 first continues energization of the lower heating element 7 by the difference in energization time between the upper heating element 6 and the lower heating element 7 (1 minute in this reference example). After that, based on the difference (13 minutes) between the newly set cooking time (17 minutes) and the cooking elapsed time (4 minutes) at that time, the energization control is alternately performed on the upper and lower heating elements according to the energization pattern when the set time is 13 minutes. Finish cooking. The energization control at that time is shown in FIG.
[0025]
Further, when 5 minutes have elapsed from the start of cooking and the upper heating element 6 is energized (arrow part), the cooking time setting means 14 is operated to newly set the cooking time to 19 minutes (14 minutes from the setting change to the end). The control means 15 obtains a time (15 minutes) from the start of energization to the upper heating element 6 to the end of cooking, and from the time when energization to the upper heating element 6 is started (4 minutes after the start of cooking). In accordance with the energization pattern when the set time is 15 minutes, the energization control is alternately performed on the upper and lower heating elements to finish cooking. The energization control at this time is shown in FIG.
[0026]
As a result, even if the cooking time is changed during cooking, the ratio of the energization time to the upper heating element and the lower heating element can be kept constant, so that the baking condition of the upper and lower surfaces of the object to be cooked can be made constant.
[0027]
(Example 2)
Next, Example 2 will be described with reference to FIG. In addition, the thing of the same structure as the said Example attaches | subjects the same code | symbol, and abbreviate | omits description.
[0028]
FIG. 6 is a diagram showing an example of the energization pattern of the upper heating element 6, the lower heating element 7 and the fan motor 10. When the control means 15 energizes the upper heating element 6 during cooking, the fan motor driving means 11 is used. When the fan motor 10 is turned off and the lower heating element 7 is energized, the fan motor driving means 11 is turned on and the fan motor 10 is rotated.
[0029]
As a result, since the fan motor 10 drives the fan motor only when the lower heating element 7 is energized, cooking can be performed while preventing the internal temperature from unnecessarily dropping.
[0030]
(Example 3)
Next, Embodiment 3 will be described with reference to FIG. In addition, the thing of the same structure as the said Example attaches | subjects the same code | symbol, and abbreviate | omits description.
[0031]
FIG. 7 is a diagram showing an example of the energization pattern of the upper heating element 6, the lower heating element 7 and the fan motor 10. The control means 15 starts energizing the lower heating element 7 and the surface temperature of the heating element increases. When the oil adhering to the surface starts to turn into oil smoke (30 seconds in this embodiment), the fan motor driving means 11 is turned on and the fan motor 10 is rotated. Further, when the energization of the lower heating element 7 is stopped (the energization of the upper heating element 6), the time during which the surface temperature of the lower heating element decreases and the oil adhering to the surface does not change to oil smoke (in this example, 1 minute) When the time has elapsed, the fan motor driving means 11 is turned off and the fan motor 10 is stopped.
[0032]
As a result, since the fan motor 10 discharges the oil smoke from the inside of the cabinet to the outside of the main body through the catalyst body only when the oil smoke is generated from the surface of the lower heating element 7, it can efficiently perform the oxidation purification action.
[0033]
【The invention's effect】
According to the first aspect of the present invention, since the fan motor is driven only when the lower heating element is energized, the effect of preventing the temperature in the refrigerator from decreasing during cooking can be obtained.
[0034]
According to the invention described in claim 2, since the fan motor is driven only when oily smoke is generated, an effect that the oxidation purification action can be performed efficiently is obtained.
