技術分野
本発明はバックミラーに関し、特に、電熱ヒータを備え
たバックミラーに関する。TECHNICAL FIELD The present invention relates to a rearview mirror, and more particularly to a rearview mirror equipped with an electric heater.
技術的背景
霧、湿気などにより曇るのを防止するだめの電熱ヒータ
を備えだバックミラーは既に仰られている。Technical Background Rearview mirrors equipped with electric heaters to prevent fogging due to fog, humidity, etc. have already been mentioned.
代表的なバックミラーは、ヒータエレメントをミラーガ
ラスｌこ付けるための接着剤がつけられた可撓性プラス
チック材のフィルム間に挟まれた銅、ニッケルクローム
、その他の金属から作られた電気抵抗ヒータエレメント
によって電気的に加熱されるようになってＳ−９、電源
に接続される端子は浴接されるか、リベット止めされる
か、または、接着剤で強化されている。A typical rearview mirror has an electrical resistance heater made of copper, nickel chrome, or other metal sandwiched between a film of flexible plastic material with adhesive to attach the heater element to the mirror glass. The terminals that are electrically heated by the element and connected to the power supply S-9 are bath-bonded, riveted, or reinforced with adhesive.
しかし、この従来のミラーは重大な欠点を有していた。However, this conventional mirror had significant drawbacks.
例えば、プラスチック材及び接着剤はヒータエレメント
により発生される熱によって劣化され、また、経時的に
劣化する。更に、可撓性プラスチック材へ端子を接続す
るの、は常には適正には行われず、そのため、その部分
に水が浸入して＆［剤やヒータエレメントを劣化させる
こともある。For example, plastic materials and adhesives are degraded by the heat generated by the heater elements and degrade over time. Additionally, the connection of the terminals to the flexible plastic material is not always done properly, allowing water to enter the area and degrade the agent and heater element.
更に、ヒータエレメントをプラスチック材のシートで挟
むので、熱の一部が当該ミラーのガラス（シート）に達
する前に消散してしまい、エネルギ消費が大きくなる。Additionally, since the heater element is sandwiched between sheets of plastic material, some of the heat is dissipated before reaching the glass (sheet) of the mirror, increasing energy consumption.
他の型式のバックミラーにおいては、自己接着テープで
ガラスの面に取り付けられるアルミニュームフォイルに
隔離して押圧される電気抵抗のワイヤによって構成され

メントがガラスカラ離れているので、この型式のミラー
は、先に述べた型式のミラーと同様に消費エネルギが大
きいという問題をＭしている。Other types of rearview mirrors have heater elements made up of electrically resistive wires that are pressed in isolation to aluminum foil that is attached to the glass surface with self-adhesive tape. However, because the heater element is separated from the glass, this type of mirror suffers from the same problem of high energy consumption as the previously mentioned types of mirrors.
第３の型式の電気ヒータ付バックミラーは、ガラスミー
トの一面に導電性ペイント層を所望のパターンに着け、
それが固化した後、電源端子、端子装置及びバイメタル
回路遮断器を取り付け、温度を一定範囲に維持するよう
にしている。これらのエレメントは導電性ペイントに溶
接され、その後、接着剤の層がつけられる。The third type of rearview mirror with electric heater has a conductive paint layer applied on one side of the glass sheet in a desired pattern.
After it solidifies, power terminals, terminal equipment and bimetallic circuit breakers are installed to maintain the temperature within a certain range. These elements are welded to conductive paint and then a layer of adhesive is applied.
しかし、この型式のミラーも次のような問題がある。す
なわち、接着剤が浴接の不規則性に５まく追従できずそ
の塗布が困難であり、熱により接着剤が劣化し、上記電
子機構制御装置が振動のために故障してしまうことがあ
る。However, this type of mirror also has the following problems. That is, the adhesive cannot follow the irregularities of the bath contact and is difficult to apply, the adhesive deteriorates due to heat, and the electronic mechanism control device may fail due to vibration.
発明の目的
本発明は、以上のような従来技術の欠点を解消し、製造

電気ヒータ付きのバックミラーを提供することを目的と
して（・る。Purpose of the Invention The purpose of the present invention is to eliminate the drawbacks of the prior art as described above, and to provide a rearview mirror with an electric heater that is easy to manufacture, highly reliable, and consumes very low energy. Ru.
発明の構成

材料の層とからなる。Structure of the Invention The rearview mirror according to the present invention includes a glass sheet and a glass sheet.
It consists of a layer of conductive paint forming a heater element on one side and a layer of a suitable material forming a reflective surface on the other side.
実施例
以下、本発明を添付図面に示した実施例に基づき詳細に
説明する。EXAMPLES Hereinafter, the present invention will be explained in detail based on examples shown in the accompanying drawings.
本発明に係るバックミラーを作るには、ミラーとしての
所望の形状含有するガラスシート１ｆ：、プレート２の
上に載せ、それにシルクスクリーンプロセスによって回
路印刷を行う。To make the rearview mirror according to the present invention, a glass sheet 1f containing the desired shape of the mirror is placed on a plate 2, and a circuit is printed thereon by a silk screen process.
ヒータエレメントの所望のパターンを有するスクリーン
３がプレート２の上に整合して載せられ、ファイバーグ
ラスの７レイク（ガラス原料）が混ぜられた銀をベース
にする導電性ペイント４がガラスシート上に塗布されて
、スクリーン３上のパターンがガラスシート上に印刷さ
れる。A screen 3 with the desired pattern of heating elements is placed in alignment on the plate 2 and a silver-based conductive paint 4 mixed with fiberglass 7 lakes is applied onto the glass sheet. The pattern on the screen 3 is then printed onto the glass sheet.
印刷の後、印刷されたガラスシートｌを載せたプレート
２はコンベアベルト６の上に載せられ、乾燥オープン７
に運ばれる。該オープンの温度はサーモスタット８によ
って制御され、ガラスシート上のペイントラ迅速に乾燥
させてヒータエレメント９を固定する。After printing, the plate 2 with the printed glass sheet l is placed on the conveyor belt 6 and dried in the open 7
carried to. The temperature of the opening is controlled by a thermostat 8, which quickly dries the paint on the glass sheet and fixes the heater element 9.
好ましくは、オープン７の温度は約６５０℃以上に保た
れ、導電性ペイント中のガラス原料を溶解し、それが固
化したときに耐摩耗性が生じるようにする。Preferably, the temperature of the open 7 is maintained above about 650° C. to melt the glass in the conductive paint and create abrasion resistance when it solidifies.
印刷されたヒータエレメント９はそれぞれ参照番号１０
．１１で示すよ５に、超音波をかけて洗われ、フレオン
蒸気中で乾燥される。この後、このガラスシートに金属
層をつける。The printed heater elements 9 each have the reference number 10
．． At step 5, as shown at 11, it is washed with ultrasonic waves and dried in Freon steam. After this, a metal layer is applied to this glass sheet.
金属層をつけるには、ガラスシート１を所要のハンガー
で保持する。このハンガーは金属層形成室１２に入る回
転装置（こ取り付けられている。To apply the metal layer, the glass sheet 1 is held with the required hangers. This hanger is attached to a rotating device that enters the metal layer forming chamber 12.

着されて反射面層を形成する。従来技術と相違し、この
ようにするとヒータエレメントはガラスシートに直接接
触するので、従来のバックミラーで消費されていた不必
妥なエネルギを無くすることができる。Within chamber 12, aluminum, chrome, or other metal is deposited on the side opposite the side on which the heater element is printed to form a reflective surface layer. Unlike the prior art, in this way the heater element is in direct contact with the glass sheet, thereby eliminating the unnecessary energy consumed by conventional rearview mirrors.
金属層形成室１２はバキュームタイプで、スパッタリン
グをこまって金属層が形成される。The metal layer forming chamber 12 is of a vacuum type, and the metal layer is formed by sputtering.
金属層形成後、ガラスシートには端子１３が所要位置に
溶接され、保護カバー１４がその上に覆せられ、その後
、ヒータエレメントが印刷された面が第２の工程を受け
る。After forming the metal layer, the glass sheet is welded with terminals 13 in place and a protective cover 14 is placed over it, after which the side printed with the heating element is subjected to a second step.
すなわち、この面をスプレィガンでエボキシペイントヲ
塗布され、その後、ガラスシート１はコンベアベルト１
６に載せられて乾燥オープン１７全通される。That is, this surface is coated with epoxy paint using a spray gun, and then the glass sheet 1 is transferred to the conveyor belt 1.
6 and passed through the drying open 17 completely.
このようにして、ヒータエレメント９の印刷された面に
は薄い保護層が形成され、ヒータエレメントを保護絶縁
する。In this way, a thin protective layer is formed on the printed side of the heating element 9, protecting and insulating the heating element.
保護カバー１４を取り外せば、リード線を端子につなぐ
だけで使用できるよう番こなる。一方のリート線は車の
シャーシに、他方はスイッチ、フユーズ等を弁して正の
電源に接続される。Once the protective cover 14 is removed, the terminal can be used simply by connecting the lead wires to the terminals. One lead wire is connected to the car chassis, and the other wire is connected to the positive power source through a switch, fuse, etc.
