本発明は電気加熱ヒータあるいはガスバーナ等

合型の電子レンジに係る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a complex microwave oven equipped with a heat source for externally heating an object to be heated, such as an electric heater or a gas burner.
例えばオーブン庫内に電気加熱ヒータを備えた

た。 For example, in a microwave oven equipped with an electric heater inside the oven, when grilling food such as fish, the inside of the food is rapidly heated using microwaves, and then the heater is switched on to heat the food outside. The heater heats from the surface side to give it an appropriate focus. Moreover, when grilling food, only one side facing the heater will be browned, so once one side is browned, open the door and flip the fish over.
The heater is heated again from the outside surface side. In this way, for grilled dishes such as "fish", a series of heating steps such as μ wave heating, heating with a heater, turning the fish over, heating with a heater, etc., was performed.

せればよい。 By the way, there is a gas sensor as a means for detecting the heating status of the object to be heated based on the concentration of exhaust gas from the oven, and this has the property of decreasing the resistance value as the gas concentration increases. In other words, cooking control can be performed by utilizing the property that as the cooking of the heated object progresses, gas generation becomes more active from the heated object.
When used as a means for detecting grilled food such as the above-mentioned "fish", it is as follows. As shown in Figure 1, μ
When the concentration of gas generated due to wave heating reaches the first level G1 , it is detected and the heater automatically shifts to heater heating. When the concentration of the generated gas reaches the second level G2 , it is detected and the focusing on one side is terminated. The user opens the door, turns the fish over, and closes the door again. Along with this, the heater is heated and the temperature is increased to the second level again.
When G 2 is reached, it can be detected and the grilling can be finished.
しかしながら、前記したように調理の途中で
「魚」を裏返しするため扉を開けるため、オーブ

かりである。 However, as mentioned above, since the door is opened to turn the fish over during cooking, the gas concentration inside the oven reaches the second level G2 , but the gas concentration inside the oven increases due to the infiltration of fresh outside air. will end up being diluted. Therefore, after the fish is turned over and the door is closed again, the gas concentration inside the oven may be below the first level G1 , and the function is set so that the heat source is automatically energized after the door is closed. If they are mixed together, cooking will restart from the microwave heating, and the food to be heated may be unnecessarily heated by the microwaves and become dry, which will only spoil the taste.
本発明はこのような点に鑑みなされたものであ

にしたものである。 The present invention has been made in view of these points, and provides a complex microwave oven that indirectly detects the heating status of a heated object based on oven exhaust gas.
Even if there is a change in the oven exhaust air when the door is opened during cooking, a predetermined heat source is energized after the door is closed.

The second terminal connected between the output terminals of
It is a DC relay. The first DC relay 2
0 is a relay that opens and closes relay switch 20-1, and the other second DC relay 21 is a relay that opens and closes relay switches 21-1 and 21-2. These three relay switches are always
It is energized as an NC contact, and is switched to an NO contact when the first or second DC relay 20, 21 is activated. By the way, relay switch 20-1 is
The NC contact is connected to the sheathed heater 2, the NO contact is connected to the microwave oscillator 1, and an AC power source of AC100V is alternatively connected to these heat sources. Relay switch 21

較器１２の出力が反転する。 The first latch circuit 24, which is a continuation means, is connected to the output side of the first comparator 12 and holds its output state, and the second latch circuit 25 is connected to the output side of the second comparator 13. connected and retains its output state. The first DC relay 20 connected to the input side of the first latch circuit 24 is connected to the first comparator 1.
When the output of No. 2 is reversed, it is deenergized and the relay switch 20-1 is switched to the NC contact side. That is, when the concentration of exhaust gas from the inside of the oven reaches the first level G1 due to the microwave heating of the object to be heated, the voltage at the connection point between the gas sensor 9 and the resistor 10 matches the reference voltage V1 , and the first level G1 is reached. The output of comparator 12 of No. 1 is inverted. Therefore, when the desired μ-wave heating is achieved, the relay switch 20-1 automatically switches the energization to the heater 2 side. Since the inverted output of the first comparator 12 is held by the first latch circuit 24,
The first DC relay 20 remains deenergized until the end of cooking. Further, the second DC relay 21 connected to the input side of the second latch circuit 25 is connected to the second comparator 1.
When the output of No. 3 is reversed, it is deenergized, and each of the relay switches 21-1 and 21-2 is switched to the NC contact side. In other words, the concentration of the exhaust gas from inside the oven due to the heater heating subsequent to the μ-wave heating increases to the second level.
When reaching level G 2 , gas sensor 9 and resistor 1
The node voltage of 0 matches the reference voltage V 2 and the output of the second comparator 12 is inverted.

2 is energized, relay switches 22-1, 2
2-3 is closed, while relay switch 22

る。 As mentioned above, while the door is opened and the fish is turned over, fresh air enters the oven chamber, causing the gas concentration to drop below the first level G1 . However, since AC power continues to be supplied to the detection circuit 3 and the holding circuit 4 by closing the relay switch 22-1 regardless of whether the door is opened or closed, the first latch circuit 24 continues to perform the first comparison. The inverted output of the device 12 continues to be held. When the door is closed again and the self-holding button switch 23 is opened, the AC relay 22 is deenergized, relay switches 22-1 and 22-3 are opened, relay switch 22-2 is closed, and the second latch circuit is activated. 25 returns to operation. Although the exhaust gas concentration inside the oven after the door is reclosed is below the first level G1 as shown in FIG. 3 , the first comparator after the door is reclosed is 12 outputs are disabled. Therefore, the first DC relay 20 remains deenergized and the relay switch 20
The heater 2 is energized again via the NC contact -1, and the focusing of the surface that has been turned to the front side proceeds.
