以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.
（実施の形態１）
図１は、本発明の第１の実施の形態における誘導加熱調理器の回路構成図を示すものである。
(Embodiment 1)
FIG. 1 shows a circuit configuration diagram of an induction heating cooker according to the first embodiment of the present invention.
図１において、電源１は２００Ｖ商用電源であり、リレーからなる第１の電源制御部１５、第２の電源制御部２５、第３の電源制御部３５およびグリル制御部２によりそれぞれ第１の誘導加熱ユニット１１、第２の誘導加熱ユニット２１、第３の誘導加熱ユニット３１およびグリルヒータ３のオン、オフの通電制御を行う。各誘導加熱ユニット１１、２１、３１はそれぞれインバータ１３、２３、３３と加熱コイル１２、２２、３２と加熱出力制御手段１４、２４、３４からなっている。２００Ｖ商用電源をインバータで高周波に変換し加熱コイルに供給し加熱コイルに対向して図示しない負荷である鍋を設置し、鍋を誘導加熱しつつ、その加熱出力をマイコンで構成された加熱出力制御手段で制御することで誘導加熱調理を実現するものである。誘導加熱ユニットの出力は第１および第２の誘導加熱ユニットは３ｋＷ、第３の誘導加熱ユニットは１．５ｋＷとしている。インバータおよび加熱出力制御手段は図示しないプリント配線板で構成している。メンテナンス性などに配慮して各誘導加熱ユニット毎にプリント配線板は別々のプリント配線板で構成している。また、図２のように本実施の形態では第１のインバータ１３、第１の加熱出力制御手段１４は第１のプリント配線板４で構成し、第２のインバータ２３、第２の加熱出力制御手段２４は第２のプリント配線板５で構成し、最も定格出力が小さい第３のインバータ３３および第３の加熱出力制御手段と第１の電源制御部１５、第２の電源制御部２５、第３の電源制御部３５、グリル制御部２は第３のプリント配線板６で構成している。インバータの定格が小さければインバータが占有するスペースも小さくできることから定格が小さなインバータと他の制御部とを同一プリント配線板に載置することを可能としている。各プリント配線板は省スペースで設置できるよう水平方向に設置かつ上下方向にそれぞれ積層するように配置している。また、第３のプリント配線板を最上層となるように配置していることから、第３のプリント配線板にあるグリル制御部とグリルとの配線が容易に行うことができ、また第３のプリント配線板にある各電源制御部の入力端子への商用電源との配線を容易に行うことができる。 In FIG. 1, a power source 1 is a 200V commercial power source, and a first induction is performed by a first power control unit 15, a second power control unit 25, a third power control unit 35, and a grill control unit 2, each of which is a relay. The energization control of turning on / off the heating unit 11, the second induction heating unit 21, the third induction heating unit 31, and the grill heater 3 is performed. Each induction heating unit 11, 21, 31 comprises inverters 13, 23, 33, heating coils 12, 22, 32, and heating output control means 14, 24, 34, respectively. A 200V commercial power source is converted to high frequency by an inverter, supplied to the heating coil, a pan (not shown) is installed facing the heating coil, and the pan is induction heated, and the heating output is controlled by a microcomputer. The induction heating cooking is realized by controlling by means. The output of the induction heating unit is 3 kW for the first and second induction heating units, and 1.5 kW for the third induction heating unit. The inverter and the heating output control means are composed of a printed wiring board (not shown). In consideration of maintainability and the like, the printed wiring board is constituted by a separate printed wiring board for each induction heating unit. Further, as shown in FIG. 2, in the present embodiment, the first inverter 13 and the first heating output control means 14 are constituted by the first printed wiring board 4, and the second inverter 23 and the second heating output control. The means 24 is composed of the second printed wiring board 5, and the third inverter 33 having the smallest rated output, the third heating output control means, the first power supply control section 15, the second power supply control section 25, the second The third power supply control unit 35 and the grill control unit 2 are configured by a third printed wiring board 6. Since the space occupied by the inverter can be reduced if the inverter rating is small, it is possible to place an inverter having a small rating and another control unit on the same printed wiring board. Each printed wiring board is installed in a horizontal direction and arranged in a vertical direction so that it can be installed in a small space. In addition, since the third printed wiring board is arranged so as to be the uppermost layer, wiring between the grill control unit and the grill on the third printed wiring board can be easily performed. Wiring with the commercial power supply to the input terminal of each power supply control part in a printed wiring board can be performed easily.
本実施の形態ではすべての電源制御部は１つのプリント配線板に設置したが、少なくとも１つの電源制御部と定格出力の小さいインバータと加熱出力制御手段を１つのプリント
配線板に設置しても本発明の効果は得られるものである。また、グリルはその熱源をヒータとしたが他の加熱手段でも本発明の効果が得られることはいうまでもない。
In this embodiment, all the power supply control units are installed on one printed wiring board. However, even if at least one power supply control unit, an inverter with a small rated output, and heating output control means are installed on one printed wiring board, The effects of the invention can be obtained. In addition, although the grill uses a heater as its heat source, it goes without saying that the effects of the present invention can be obtained with other heating means.
以上のように、本発明にかかる誘導加熱調理器は、複数の誘導加熱ユニットをスペース効率よく搭載可能となるので、工業用誘導加熱等の用途にも適用できる。 As described above, the induction heating cooker according to the present invention can be installed in a plurality of induction heating units in a space-efficient manner, and can be applied to uses such as industrial induction heating.
