ここで、リレー51.52.53.54.55の具体的
な構成を第1図および第2図に示す。Here, the specific configuration of the relays 51, 52, 53, 54, 55 is shown in FIGS. 1 and 2.
61は本体で、1字形の台座62を備えている。台座6

磁コイル64が巻回される。励磁コイル64は、一端側
に端子65、他端側に端子66を有している。Reference numeral 61 denotes a main body, which is provided with a 1-shaped pedestal 62. Pedestal 6
An iron core 63 is erected at the bottom of 2, and an excitation coil 64 is wound around the iron core 63. The excitation coil 64 has a terminal 65 at one end and a terminal 66 at the other end.
そして、端子66に抵抗90の一端が接続され、抵抗9
0の他端には端子67が接続されている。One end of a resistor 90 is connected to the terminal 66, and the resistor 90
A terminal 67 is connected to the other end of 0.
台座62の立位部には鉄芯63の上端部と対向するよう
に可動板68が設けられる。この可動板68は、鉄製の
もので、台座62の立位部に上下回動自在に取付けられ
ており、スプリング69によって上方向への偏倚力を受
け、通常は鉄芯63から離間するようになっている。ま
た、可動板68に可動接片70が設けられ、その可動接
片70の下方には固定端子71が配設される。そして、
可動接片70は固定端子72にリード線接続される。つ
まり、固定端子71.72間に常開接点73が形成され
る。A movable plate 68 is provided at the upright portion of the pedestal 62 so as to face the upper end of the iron core 63. This movable plate 68 is made of iron and is attached to the upright portion of the pedestal 62 so as to be able to move up and down.It receives an upward biasing force from a spring 69, and normally moves away from the iron core 63. It has become. Further, a movable contact piece 70 is provided on the movable plate 68, and a fixed terminal 71 is provided below the movable contact piece 70. and,
The movable contact piece 70 is connected to a fixed terminal 72 by a lead wire. In other words, a normally open contact 73 is formed between the fixed terminals 71 and 72.
さらに、可動板68に絶縁体74を介して接片80が設
けられる。この接片80は、導電体で成形されており、
消勢時は励磁コイル64の端子66に接触し、付勢時は
端子67に対する接触へと移り変わるようになっている
。そして、接片80に端子81が接続されている。Further, a contact piece 80 is provided on the movable plate 68 with an insulator 74 in between. This contact piece 80 is made of a conductive material,
When deenergized, it contacts the terminal 66 of the excitation coil 64, and when it is energized, the contact changes to the terminal 67. A terminal 81 is connected to the contact piece 80.
なお、リレー53のように双方向性接点を有する場合は
、可171接片70の近傍に固定端子がもう一つ増える
ことになる。Note that when the relay 53 has a bidirectional contact, one more fixed terminal is added near the contact piece 70.
つぎに、上記のような構成において作用を説明する。Next, the operation in the above configuration will be explained.
端子65.81間に直流電圧VdCを印加すると、励磁
コイル64aが励磁され、鉄芯63が磁化される。When DC voltage VdC is applied between terminals 65 and 81, exciting coil 64a is excited and iron core 63 is magnetized.
この場合、直流電圧Vdcの印加に際しては接片80が
まず端子66に接触しているので、励磁コイル64のみ
への通電がなされる。したがって、励磁コイル64に大
きな′R流が流れ、鉄芯63に大きな起磁力が発生する
。鉄芯63が磁化されると、それに可動板68が吸着さ
れる。可動板68が吸着されると、可動接片70が固定
端子71に接触し、固定端子71.72間が電気的に導
通する。つまり、常開接点γ3がオンする。In this case, since the contact piece 80 is first in contact with the terminal 66 when applying the DC voltage Vdc, only the excitation coil 64 is energized. Therefore, a large 'R current flows through the exciting coil 64, and a large magnetomotive force is generated in the iron core 63. When the iron core 63 is magnetized, the movable plate 68 is attracted to it. When the movable plate 68 is attracted, the movable contact piece 70 comes into contact with the fixed terminal 71, and the fixed terminals 71 and 72 are electrically connected. In other words, the normally open contact γ3 is turned on.
また、鉄芯63に可動板68が吸着されると、第3図お
よび第4図に示すように、接片80が端子66に対する
接触から端子67に対する接触へと移り変わる。この場
合、接片80が端子61と接触する時点において、接片
80はまだ端子66との接触状態を保っており、よって
励磁コイル64への通電が途切れることはない。Further, when the movable plate 68 is attracted to the iron core 63, the contact piece 80 changes from contacting the terminal 66 to contacting the terminal 67, as shown in FIGS. 3 and 4. In this case, when the contact piece 80 comes into contact with the terminal 61, the contact piece 80 is still in contact with the terminal 66, so that the energization to the excitation coil 64 is not interrupted.
こうして、接片80が端子61に接触すると、励磁コイ
ル64および抵抗90の直列回路への通電がなされる。In this way, when the contact piece 80 comes into contact with the terminal 61, the series circuit of the exciting coil 64 and the resistor 90 is energized.
この直列回路への通電は、可動板G8の吸着保持にはそ
れほど大きな起磁力が必要でないことを考慮したもので
(ヒステリシスに基づいており、印加電圧が直流の場合
に顕著)、励磁コイル64に流れる電流を抑制するもの
である。This series circuit is energized in consideration of the fact that a large magnetomotive force is not required to attract and hold the movable plate G8 (this is based on hysteresis, and is noticeable when the applied voltage is DC). This suppresses the flowing current.
直流電圧VdCの印加を解除すると、鉄芯63の磁化が
解除され、鉄芯63から可動板68が離れる。すると、
可動接片70が固定端子11から離れ、固定端子71.
72間の電気的導通が解除される。つまり、常開接点1
3がオフする。When the application of the DC voltage VdC is removed, the magnetization of the iron core 63 is released, and the movable plate 68 is separated from the iron core 63. Then,
The movable contact piece 70 separates from the fixed terminal 11, and the fixed terminal 71.
Electrical continuity between 72 is broken. In other words, normally open contact 1
3 is off.
このように、大きな起磁力を必要とする接点駆動に際し
ては励磁コイル64のみへの通電を行なうが、大きな起
磁力を必要としない接点駆動後は励磁コイル64および
抵抗90の直列回路への通電を行なうことにより、消費
電力を小さくすることができる。したがって、第5図の
制御回路のように多数個のリレーを使用する状況であっ
ても、制御部40におけるii源ヒトランス41大形の
ものにする必要は全くない。つまり、コストの上昇を抑
えることができ、しかも制御部40が搭載される制御回
路基板の大形化、ひいては電子レンジ本体の大形化を防
ぐことができる。In this way, when driving the contacts that require a large magnetomotive force, only the excitation coil 64 is energized, but after contact driving that does not require a large magnetomotive force, the series circuit of the excitation coil 64 and the resistor 90 is not energized. By doing so, power consumption can be reduced. Therefore, even in a situation where a large number of relays are used as in the control circuit shown in FIG. 5, there is no need to make the II source transformer 41 large in the control section 40. In other words, an increase in cost can be suppressed, and furthermore, it is possible to prevent the control circuit board on which the control section 40 is mounted from increasing in size, and furthermore, it is possible to prevent the microwave oven main body from increasing in size.
