Description

本発明は高周波加熱装置の電流ヒューズ部の構成に関するものである。   The present invention relates to a configuration of a current fuse portion of a high-frequency heating device.

従来の高周波加熱装置の一例を図7に示す(例えば、特許文献1参照)。   An example of a conventional high-frequency heating device is shown in FIG. 7 (see, for example, Patent Document 1).

図7は、特許文献1に記載された従来の高周波加熱装置のノイズフィルター基板の正面図である。図7に示すように、プリント基板1にリード付き電流ヒューズ2がハンダ付けされている。   FIG. 7 is a front view of a noise filter substrate of a conventional high-frequency heating device described in Patent Document 1. As shown in FIG. 7, a current fuse 2 with leads is soldered to the printed circuit board 1.

もう一例を図8に示す(例えば、特許文献2参照)。   Another example is shown in FIG. 8 (see, for example, Patent Document 2).

図8は、特許文献2に記載された従来の高周波加熱装置のノイズフィルター基板の斜視図である。図8に示すように、プリント基板1にヒューズホルダー9がハンダ付けされており、ヒューズホルダー9には管形電流ヒューズ10が嵌め込まれている。   FIG. 8 is a perspective view of a noise filter substrate of a conventional high-frequency heating device described in Patent Document 2. As shown in FIG. 8, a fuse holder 9 is soldered to the printed circuit board 1, and a tubular current fuse 10 is fitted in the fuse holder 9.

特開平11−159767号公報Japanese Patent Laid-Open No. 11-159767 特開平6−29084号公報JP-A-6-29084

しかしながら、前記従来の構成では、電流ヒューズ2にリード付き電流ヒューズを使用した場合、プリント基板1にハンダ付けされているので、市場で電流ヒューズ2が溶断し、部品交換サービスする時に、最近はハンダ付けの信頼性などの観点から、リード付き電流ヒューズのみを交換する事はほとんどなく、プリント基板1ごとの交換が通例であり、サービス費用が高くなるという課題を有していた。なお、上記従来例はノイズフィルター基板にリード付きヒューズがハンダ付けされているが、高周波加熱装置の制御基板にリード付きヒューズがハンダ付けされている場合も多々あり、その場合は、制御基板の方がノイズフィルター基板より、より高価なのでサービス費用がさらに高くなるという課題を有していた。   However, in the conventional configuration, when a current fuse with a lead is used as the current fuse 2, it is soldered to the printed circuit board 1. Therefore, when the current fuse 2 is melted in the market and parts replacement service is performed, a solder is recently used. From the standpoint of attachment reliability and the like, there is almost no need to replace only the leaded current fuse, and replacement of each printed circuit board 1 is common, and there is a problem that service costs are high. In the above conventional example, the fuse with lead is soldered to the noise filter substrate, but there are many cases where the fuse with lead is soldered to the control substrate of the high-frequency heating device. However, since it is more expensive than the noise filter substrate, there is a problem that the service cost is further increased.

一方、電流ヒューズ2に管形電流ヒューズ10を使用した場合は、ヒューズホルダー9が必要だが、電気用品安全法によって、ヒューズホルダー9と管形電流ヒューズ10の接触部の温度上昇には、温度限度が設けられているので、管形電流ヒューズ10を冷却するために、冷却ファンによる冷却をしたり、冷却したりするための部品を追加するなど、性能面での制約やコスト高になるという課題を有していた。   On the other hand, when the tubular current fuse 10 is used as the current fuse 2, the fuse holder 9 is necessary. However, due to the Electrical Appliance and Material Safety Law, the temperature rise at the contact portion between the fuse holder 9 and the tubular current fuse 10 is a temperature limit. Because of this, there are performance limitations and high costs, such as cooling with a cooling fan or adding parts for cooling in order to cool the tubular current fuse 10 Had.

本発明は、リード付きヒューズを使用することにより、電気用品安全法による温度限度はないので、ヒューズを冷却するための性能面での制約やコスト高になる事がなく、かつ市場でヒューズが溶断し交換サービスする時でも、プリント基板ごとの交換が不要で、ヒューズのみを交換する事が出来るので、サービス費用も安価ですむ高周波加熱装置を提供することを目的とする。   Since the present invention uses a leaded fuse, there is no temperature limit according to the Electrical Appliance and Material Safety Law, so there is no performance limitation or cost increase for cooling the fuse, and the fuse is blown in the market. However, it is an object of the present invention to provide a high-frequency heating device that does not require replacement for each printed circuit board and can replace only the fuse, so that the service cost is low.

前記従来の課題を解決するために、本発明の高周波加熱装置は、プリント基板上にリー

In order to solve the above-described conventional problems, the high-frequency heating device of the present invention is provided with a leaded current fuse on a printed circuit board, and provided with eyelets electrically connected to both ends of the leaded current fuse, Alternatively, each of the current fuses with leads is electrically connected to both ends, and each of them is provided with a pattern in which lands are provided in part, and by providing holes in the lands, there is no temperature limit according to the Electrical Appliance and Material Safety Law. There are no performance restrictions or cost increases for cooling.

また、市場でヒューズが溶断し交換サービスする時は、リード付き電流ヒューズの両端に電気的に接続されたハトメ、もしくはリード付き電流ヒューズの両端に電気的に接続され、一部にランドを設けたパターンを各々設けると共に、前記ランドに設けた穴に、サービス専用のリードの両端にめがね端子を接続したリード付き電流ヒューズのめがね端子をねじ止めする事により、ヒューズのみの交換が可能となり、プリント基板ごとの交換は不要になるので、サービス費用も安価ですむものである。   Also, when fuses are blown and replaced in the market, eyelets that are electrically connected to both ends of the current fuse with leads, or electrically connected to both ends of the current fuse with leads, and lands are provided in part. By providing each pattern and screwing the glasses terminal of the lead current fuse with the glasses terminal connected to both ends of the service dedicated lead in the hole provided in the land, it is possible to replace only the fuse, Since there is no need to replace each unit, the service cost is also low.

本発明の高周波加熱装置は、プリント基板上にリード付き電流ヒューズを設けると共に、前記リード付き電流ヒューズの両端に電気的に接続されたハトメを各々設けるか、もしくは前記リード付き電流ヒューズの両端に電気的に接続され、一部にランドを設けたパターンを各々設けると共に、前記ランドに穴を設ける事により、電気用品安全法による温度限度はないので、ヒューズを冷却するための性能面での制約やコスト高になる事はなくなる。   In the high-frequency heating device of the present invention, a current fuse with leads is provided on a printed circuit board, and eyelets electrically connected to both ends of the current fuse with leads are provided, respectively, or both ends of the current fuse with lead are electrically connected. Since there are no temperature limits according to the Electrical Appliance and Material Safety Law, each of the lands is provided with a pattern in which lands are partly connected, and the lands are provided with holes. It will not be expensive.

また、市場でヒューズが溶断し交換サービスする時は、リード付き電流ヒューズの両端に電気的に接続されたハトメ、もしくはリード付き電流ヒューズの両端に電気的に接続され、一部にランドを設けたパターンを各々設けると共に、前記ランドに設けた穴に、サービス専用のリードの両端にめがね端子を接続したリード付き電流ヒューズのめがね端子をねじ止めする事により、ヒューズのみの交換が可能となり、プリント基板ごとの交換は不要になるので、サービス費用も安価ですむものである。   Also, when fuses are blown and replaced in the market, eyelets that are electrically connected to both ends of the current fuse with leads, or electrically connected to both ends of the current fuse with leads, and lands are provided in part. By providing each pattern and screwing the glasses terminal of the lead current fuse with the glasses terminal connected to both ends of the service dedicated lead in the hole provided in the land, it is possible to replace only the fuse, Since there is no need to replace each unit, the service cost is also low.
