実施例
以下本発明の一実施例である電気ストーブについて図面
を用いて説明する。EXAMPLE An electric stove which is an example of the present invention will be described below with reference to the drawings.
第1図は電気ストーブの制御回路のブロック図である。FIG. 1 is a block diagram of a control circuit for an electric stove.
第2図は発熱体の通電タイミングチャートである。図に
おいて1は交流電源であり、これに発熱体5,7.9が
並列に接続され、発熱体5゜7の通電回路にはそれぞれ
トライアック6.8が挿入され、発熱体9には連続通電
制御スイッチ10が接続されている。2は電源スィッチ
である。FIG. 2 is a timing chart for energizing the heating element. In the figure, 1 is an AC power supply, to which heating elements 5 and 7.9 are connected in parallel, a triac 6.8 is inserted in each of the energizing circuits of the heating elements 5 and 7, and the heating element 9 is continuously energized. A control switch 10 is connected. 2 is a power switch.
1はトリガ回路であり、ゼロクロストリガパルス発生回
路3と通電制御回路4とで構成されている。Reference numeral 1 denotes a trigger circuit, which is composed of a zero-cross trigger pulse generation circuit 3 and an energization control circuit 4.
上記構成で連続通電制御スイッチ10を閉にしておけば
発熱体9は連続通電状態となる。ゼロクロストリガパル

6を導電させる。次に第2図に示すタイミングにて順次
発熱体7,5.7・・・・・・と通電していく。したが
って消費電力はそれぞれの発熱体の容量が同一であれば
常に2個分となる。With the above configuration, if the continuous energization control switch 10 is closed, the heating element 9 is continuously energized. The zero cross pulse generated by the zero cross trigger pulse generation circuit 3 causes the energization control circuit 4 composed of a microcomputer etc. to generate a trigger pulse at the zero cross, and the power control element generates a trigger pulse for 0.3 seconds (18 cycles in a 60 Hz area). A certain triac 6 is made conductive. Next, the heating elements 7, 5, 7, . . . are sequentially energized at the timing shown in FIG. Therefore, if the capacity of each heating element is the same, the power consumption is always equal to that of two heating elements.

熱体をm個とし、通電制御回路により制御される発熱体
(n−m)個のうち常にβ個分の消費電力となるように
すれば全体の消費電力は常に(m+l)個分の消費“心
力になることは言うまでもない。When there are many (n) heating elements, the number of heating elements that are continuously energized is m, and the power consumption is always equal to β of the (n-m) heating elements controlled by the energization control circuit. It goes without saying that if you do this, the total power consumption will always be equivalent to (m+l) energy consumption.

かである。In this embodiment, control was performed in units of one cycle, but the same applies to units of half cycles. Furthermore, it is clear that if the heating element that is continuously energized is placed at the bottom and the heating element whose energization is controlled by a trigger circuit is placed at the top, it will be closer to a natural flame.
