Abstract

PURPOSE:To enable to shorten the rise time of a cooker by a method wherein both a grill heater provided at the upper part of a heating chamber and a hot air circulating heater provided outside the heating chamber are simultaneously energized only during the period of time until the temperature in the heating chamber reaches the cooking set temperature. CONSTITUTION:During the hot air circulating mode, an air heater 5 is energized so as to send the heated air in an oven 2 by means of a hot air fan 6 in order to raise the temperature in the oven 2. However, at the rise time of the mode, a grill heater 8 is also energized at the same time. Though the temperature in the oven 2 does not rise before the temperature onto the wall surface in the oven 2 because the hot air flows along the wall surface in the oven 2, the grill heater 8 can directly heat the air in the oven because the grill heater is attached at the upper part in the oven 2, resulting in enabling to shorten the rise time by the time assisted by heating with the grill heater. At the rise time of the combination cooking mode, an electronic range is turned OFF before the temperature in the oven 2 reaches the set temperature, because the input power may be too large if the hot air heater 5, the grill heater 8 and the electronic range are simultaneously turned ON.

作している事を示す。11 is a 7 motor for cooling electrical parts and is controlled by a relay chain. 1 is a relay for controlling the operation of the microwave oven function, and SW1 and SW are switches that operate in conjunction with the opening and closing of the door 3 to stop the operation of each component when the door 3 is opened. Also, C is a printed circuit board circuit equipped with a microcomputer, and relays R1 to Re
SW2 is a switch that allows the microcomputer to recognize the open/closed state of the door 3. Deaf 4 is a safety switch that short-circuits the power supply circuit when switches SWI and SW2 have a defect such as welding, melting the fuse and making the set inoperable. 4 is a high frequency oscillator operated by a microwave oven motor, and 15, 16 and 17 are a high voltage transformer, a high voltage capacitor and a diode, respectively, for supplying power to the high frequency oscillator. The table below shows the operating status of each relay in each cooking mode, and a circle indicates that the relay is operating.

熱風循環モードとコンビネーションモードの立ち上がり

リルヒータ８が同時に通電される事を示す。When the hot air circulation mode and the combination mode start, both the relay tap and R3 are on the same side, indicating that the hot air heater 5 and the grill heater 8 are energized at the same time.

以下上記構成における作用について説明する。The operation of the above configuration will be explained below.

設定時に熱風ヒータ５のみを通電するだけでは１４〜１
５分の立ち上がり時間を要するものが５〜６分程度まで
短縮する事が出来る。これは二つのヒータの消費電力を
ほぼ等しくした場合であるが、単に消費電力が２倍にな
った以上に立ち上がり時間の短縮効果がある事が判る。In the hot air circulation mode, the hot air heater 5 is energized, and the heated air is transferred to the oven 2 by the hot air fan 5.
When the internal temperature reaches the set temperature, the grill heater 3 is also energized at the same time, so the temperature inside the oven 2 increases.
If only the hot air heater 5 is energized at the time of setting, 14 to 1
What takes 5 minutes to rise can be shortened to about 5 to 6 minutes. This is a case where the power consumption of the two heaters is approximately equal, but it can be seen that the effect of shortening the start-up time is greater than simply doubling the power consumption.

その理由は熱風循環の場合は熱風がオーブン２内の壁面
にそって流れる為、壁面の温度が上がってからでないと
庫内の温度も上がらないが、グリルヒータ８は庫内上部
につけられている為、直接庫内の空気を暖める事が出来
、その分立ち上がり時間を早める事が出来る為である。The reason for this is that in the case of hot air circulation, the hot air flows along the walls inside the oven 2, so the temperature inside the oven does not rise until the temperature of the walls rises, but the grill heater 8 is attached to the top of the oven. This is because the air inside the refrigerator can be directly warmed, and the start-up time can be accelerated accordingly.

８及び電子レンジの三つが同時に入ってしまうと入力電
力が大きくなり過ぎる為、第３図に示すように庫内温度

ている。At the start of combination cooking, in which the microwave oven and hot air circulation are turned on at the same time, if the hot air heater 5, grill heater 8, and microwave oven are turned on at the same time, the input power will be too large. The microwave oven is turned off until the temperature reaches the set temperature.
