(イ) 産業上の利用分野
本考案は誘導加熱調理器に使用される電気部品
の放熱を図る放熱構造に関する。[Detailed Description of the Invention] (a) Industrial Application Field The present invention relates to a heat radiation structure for dissipating heat from electrical components used in induction heating cookers.
(ロ) 従来技術
誘導加熱調理器は交流電源を整流器を用いて直

加熱するものである。(b) Prior art The induction heating cooker converts AC power into DC using a rectifier, and then supplies this DC voltage to an inverter to turn ON and OFF the switching elements in the inverter. A current is generated to generate a high-frequency alternating magnetic field in a heating coil included in the inverter device, thereby inductively heating a cooking utensil made of ferrous metal placed close to the heating coil.
ところで、このような誘導加熱調理器において
整流器、スイツチング素子は発熱量が多く、しか
もこれ等は半導体素子で構成されている為、熱に
弱いと云う性質があつた。このため、従来はこれ
等の整流器、スイツチング素子を夫々別々の放熱

られていた。ところがこのように各電気部品毎に
放熱板を設けると、その分だけスペースが必要に
なり、調理器の小型化を阻害するものであつた。 Incidentally, in such an induction heating cooker, the rectifier and switching elements generate a large amount of heat, and since they are constructed of semiconductor elements, they are susceptible to heat. For this reason, a conventional structure has been adopted in which these rectifiers and switching elements are attached to separate heat sinks to increase the heat dissipation effect. However, when a heat sink is provided for each electric component in this manner, a corresponding space is required, which hinders the miniaturization of the cooker.
このため、整流器、スイツチング素子等の電気
部品を一枚の放熱板に取り付けると云う構成が考
えられるが、このような構成を採ると、スイツチ
ング素子と整流器の放熱量の差異により、発熱量
の少い方の電気部品が発熱量の多い方の電気部品
から熱を受けると云う不都合があつた。 For this reason, a configuration may be considered in which electrical components such as a rectifier and a switching element are attached to a single heat sink, but if such a configuration is adopted, the amount of heat generated will decrease due to the difference in heat dissipation between the switching element and the rectifier. There was an inconvenience in that the electrical components on the other side received heat from the electrical components that generated more heat.
(ハ) 考案の目的
本考案はこのような点に鑑みて為されたもので

(ニ) 考案の構成
本考案は放熱板上に複数の電気部品を離間して

肉薄部に放熱フインを設けた構成を採つている。(d) Structure of the invention The invention adopts a structure in which a plurality of electrical components are mounted at a distance on a heat sink, a thin wall is formed between the mounting parts, and a heat sink is provided in this thin wall.

is provided. Reference numeral 4 denotes a thin part formed between the switching element mounting part 2 and the rectifier mounting part 3 of the heat sink 1. If the thickness A of the mounting part is, for example, 4 mm, the thickness B of the thin part 4 is is thinner at 2mm. Further, this thin portion 4 is provided with a large number of heat radiation fins 5, 5, . . . . A rectifier 6 is attached to the rectifier attachment portion 3 by screws or the like, and is composed of a diode bridge for full-wave rectification of the AC power source. 7 is a thyristor screwed to the switching element mounting portion 2 of the heat sink 1;
A switching element made of a transistor or the like is shown, and is part of an inverter device driven using the pulsating voltage generated by the rectifier 3. 8
is a control board disposed near the switching element mounting portion 2, and has a structure in which the switching element 7 is electrically connected via an electrode lead 9, and is formed on this control board 8. A control circuit (not shown) controls the switching element 7.
ON and OFF are controlled.

The generated heat is transmitted to the heat radiation fins 5, 5, . . . of the thin wall portion 4 of the heat radiation plate 1 and is efficiently radiated. Further, when the amount of heat generated by one electrical component, for example, the rectifier 1, is greater than that of the other electrical component, ie, the switching element 7, a large amount of heat is supplied from the rectifier 6 side to the thin portion 4. However, since this thin wall portion 4 has a high thermal resistance, the heat generated in the rectifier 6 does not go beyond this thin wall portion 4 and is transmitted to the switching element 7 side, and all of the heat is radiated by the heat radiation fins 5, 5.

Since the heat emitted from these electrical components is completely radiated by the heat dissipation fins, multiple electrical components can be dissipated by one heat dissipation fin without being affected by the thermal effects of other electrical components. It can be mounted on a board, making the heat dissipation structure more compact.
