Description

本発明は、浴室の壁等に設置される浴室テレビに関する。   The present invention relates to a bathroom television set on a bathroom wall or the like.

浴室テレビは液晶からなる映像表示部を備えている。なお、浴室は常に湯水がかかる環境であるため、この映像表示部を含めて電子回路等の全てが防水ケーシング内に収納されている。そして、この防水ケーシングの前面には透明な窓部が形成され、この窓部を通して映像表示部を鑑賞するように構成されている。   The bathroom TV has an image display unit made of liquid crystal. Since the bathroom is always in a hot and cold environment, all of the electronic circuits including the video display unit are stored in the waterproof casing. A transparent window portion is formed on the front surface of the waterproof casing, and the video display portion is viewed through the window portion.

浴室用テレビは上述のように常に湯水がかかるほか、浴室内にミストを発生させるサウナ装置が浴室に設置されている場合には、特に窓部の外面に水滴が多数付着し、映像表示部を鑑賞しづらくなという不具合が生じる。   As described above, bathroom TVs are always exposed to hot water, and when a sauna device that generates mist in the bathroom is installed in the bathroom, many water droplets adhere to the outer surface of the window, and the video display section There is a problem that it is difficult to watch.

従来の浴室テレビではこのような窓部に付着した水滴を除去する手段が提案されていなかったが、浴室に設置される鏡の防曇構造として、鏡の前方にさらに透明な前板を設け、この透明板の後面を全面にわたって透明なヒータ被膜で覆い、このヒータ被膜に通電して前板を加熱することにより前板の前面に付着した水滴等を除去するようにしたものが知られている（例えば、特許文献１参照）。
特開２００３−３３９４９６号公報（図１） In conventional bathroom televisions, no means for removing such water droplets attached to the window has been proposed, but as a mirror defogging structure installed in the bathroom, a more transparent front plate is provided in front of the mirror, It is known that the rear surface of the transparent plate is covered with a transparent heater film over the entire surface, and water drops attached to the front surface of the front plate are removed by energizing the heater film and heating the front plate. (For example, refer to Patent Document 1).
Japanese Patent Laid-Open No. 2003-339496 (FIG. 1)

上記鏡の防曇構造を浴室テレビに適用することは可能であるが、上記従来のものでは透明なヒータ被膜を前板の後面全体に被着しているため、電流分布が均一になりづらく、均一な発熱が望めない。そのため、防曇効果が強く発揮される箇所とそうでない箇所とが生じ、映像表示部を鑑賞する際の妨げになるおそれが生じる。   Although it is possible to apply the anti-fogging structure of the mirror to a bathroom TV, in the above-mentioned conventional one, since the transparent heater film is applied to the entire rear surface of the front plate, the current distribution is difficult to be uniform. Uniform heat generation cannot be expected. For this reason, a portion where the anti-fogging effect is exerted strongly and a portion where the anti-fogging effect is exerted are generated, which may hinder the viewing of the video display unit.

そこで本発明は、上記の問題点に鑑み、均一な防曇効果が望める浴室テレビを提供することを課題とする。   Then, this invention makes it a subject to provide the bathroom television which can expect the uniform anti-fog effect in view of said problem.

上記課題を解決するために本発明による浴室テレビは、浴室に設置される浴室用テレビであって、映像表示部の前方に透明な窓部を備えた防水ケースに収納されたものにおいて、窓部を前後に所定の間隔を存して配置された２枚の透明板で構成すると共に、透明な帯状のヒータ被膜を外側の透明板の内面の全域を覆うように曲折させて被着させ、ヒータ被膜が被着されていない部分にヒータ被膜と同じ材料を、ヒータ被膜との間に絶縁膜を介して被着させたことを特徴とする。   In order to solve the above problems, a bathroom television according to the present invention is a bathroom television installed in a bathroom, and is housed in a waterproof case having a transparent window in front of a video display portion. Is formed of two transparent plates arranged at a predetermined interval on the front and back, and a transparent belt-like heater film is bent and applied so as to cover the entire inner surface of the outer transparent plate. It is characterized in that the same material as the heater film is applied to a portion where the film is not applied via an insulating film between the heater film.

ヒータ被膜を帯状とすることにより電流密度が均一になり、発熱にムラが生じない。ただし、ヒータ被膜を曲折させて設けると、ヒータ被膜が被着されている部分とされていない部分とが生じる。ヒータ被膜の屈折率は空気の屈折率と相違するので、映像表示部を観る際にヒータ被膜が被着されている部分とされていない部分とがわかり、鑑賞に支障が生じる場合が生じる。そこで、ヒータ被膜が被着されていない部分にヒータ被膜と同じ材料を、ヒータ被膜との間に絶縁膜を介して被着させ、全体の屈折率が同じになるようにした。   By making the heater film into a strip shape, the current density becomes uniform and heat generation is not uneven. However, when the heater film is bent and provided, a part where the heater film is applied and a part where the heater film is not formed are generated. Since the refractive index of the heater film is different from the refractive index of air, when the image display unit is viewed, it can be seen that the heater film is not attached to the part, and there are cases where the viewing is hindered. In view of this, the same material as the heater film is applied to the portion where the heater film is not applied through an insulating film between the heater film and the entire refractive index is made the same.

また、上記課題を解決するために本発明による他の浴室テレビは、浴室に設置される浴室用テレビであって、映像表示部の前方に透明な窓部を備えた防水ケースに収納されたものにおいて、窓部を前後に所定の間隔を存して配置された２枚の透明板で構成すると共に、両透明板の間に透明な液状の熱媒を充填し、かつこの熱媒を加熱するヒータとして、内側の透明板の前面を全域にわたって覆うように被着した透明なヒータ被膜を設けたことを特徴とする。 In order to solve the above problems, another bathroom television according to the present invention is a bathroom television installed in a bathroom, and is housed in a waterproof case having a transparent window portion in front of the video display portion. The window portion is composed of two transparent plates arranged at a predetermined interval on the front and rear, and a transparent liquid heat medium is filled between both transparent plates, and the heater is used as a heater for heating the heat medium. A transparent heater film is provided so as to cover the entire front surface of the inner transparent plate .

この構成では、熱媒を介して外側の透明板を加熱するので、均一に加熱することができる。   In this configuration, since the outer transparent plate is heated via the heat medium, it can be heated uniformly.

なお、上記熱媒を加熱するヒータを、内側の透明板の前面を全域にわたって覆うように被着した透明なヒータ被膜で構成する。 Incidentally, a heater for heating the upper Symbol heat medium is made of a transparent heater film was applied over the front surface of the inner transparent plate over the entire region.

以上の説明から明らかなように、本発明は、前板を均一に加熱することができ、むら無く防曇を行うことができる。   As is apparent from the above description, the present invention can uniformly heat the front plate and can perform anti-fogging without unevenness.

図１を参照して、１は本発明による浴室用テレビであり、浴室の壁面ＢＲに固定されている。この浴室用テレビ１は、図２に示すように、前ケース２と後ケース３とからなる防水ケーシング内に回路基板４が収納されている。そして、この回路基板４上に映像表示部である液晶表示ユニット４１が設けられている。   Referring to FIG. 1, reference numeral 1 denotes a bathroom television according to the present invention, which is fixed to a bathroom wall BR. As shown in FIG. 2, the bathroom television 1 includes a circuit board 4 housed in a waterproof casing including a front case 2 and a rear case 3. A liquid crystal display unit 41 as a video display unit is provided on the circuit board 4.

前ケース２にはこの液晶表示ユニット４１に表示されるテレビ画像を鑑賞するための透明な窓部５が形成されている。なお、１１は化粧カバーである。   The front case 2 is formed with a transparent window 5 for viewing a television image displayed on the liquid crystal display unit 41. Reference numeral 11 denotes a decorative cover.

図３を参照して、この窓部５は２枚の透明板５１，５２で構成されている。両透明板５１，５２の間には隙間５３が形成されており、さらに前側の透明板５１の後面にはヒータ被膜６が被着されている。このヒータ被膜は透明な導電材料で構成されている。そして、窓部５を前方から観ると、図４に示すように、帯状のヒータ被膜６が曲折されて窓部５のほぼ前面を覆うように被着されている。そして、電源６２から通電するとこのヒータ被膜６が発熱して前側の透明板５１が加熱される。６３はスイッチであり、必要に応じて通電し、あるいは通電を停止する。   Referring to FIG. 3, this window portion 5 is composed of two transparent plates 51 and 52. A gap 53 is formed between the two transparent plates 51 and 52, and the heater film 6 is applied to the rear surface of the front transparent plate 51. This heater film is made of a transparent conductive material. And when the window part 5 is seen from the front, as shown in FIG. 4, the strip | belt-shaped heater film 6 is bent and is attached so that the front surface of the window part 5 may be covered. When energized from the power source 62, the heater film 6 generates heat and the front transparent plate 51 is heated. 63 is a switch which energizes or stops energization as necessary.

ところで、図４に示すように、帯状のヒータ被膜６を曲折して設けると、ヒータ被膜６が被着されない部分が生じる。そこで、図５に示すように、ヒータ被膜６を透明板５１の後面に被着させたあと、透明な絶縁層７でヒータ被膜６を覆い、その後にヒータ被膜６が被着されていない部分に、ヒータ被膜６と同じ材料からなる中間部６１を被着させた。これにより、ヒータ被膜６が被着されている部分とそれ以外の部分との屈折率が相互に同一となり、液晶表示ユニット４１の映像を鑑賞する際に違和感が生じない。   By the way, as shown in FIG. 4, when the belt-shaped heater film 6 is bent and provided, a portion where the heater film 6 is not deposited is generated. Therefore, as shown in FIG. 5, after the heater film 6 is deposited on the rear surface of the transparent plate 51, the heater film 6 is covered with a transparent insulating layer 7, and then the heater film 6 is not deposited on the portion. The intermediate part 61 made of the same material as the heater film 6 was deposited. Thereby, the refractive index of the part to which the heater film 6 is applied and the other part are the same, and there is no sense of incongruity when viewing the image of the liquid crystal display unit 41.

また、上記構成の他、例えば、図６に示すように、後側の透明板５２の前面を全域にわたって透明なヒータ被膜８で覆うと共に、隙間５３に熱媒としてシリコンオイルを充填してもよい。この構成では、ヒータ被膜８は透明板５２の前面の全域を覆うので従来のもののように加熱ムラが生じるおそれがあるが、熱媒であるシリコンオイルを介して透明板５１が加熱されるので、透明板５１に対する加熱ムラは生じない。なお、シリコンオイルが加熱され膨張すると隙間５３内の圧力が上昇するので、隙間５３に通ずるバッファタンク９を設けることが望ましい。   In addition to the above configuration, for example, as shown in FIG. 6, the front surface of the rear transparent plate 52 may be covered with a transparent heater film 8 over the entire area, and the gap 53 may be filled with silicon oil as a heat medium. . In this configuration, since the heater film 8 covers the entire front surface of the transparent plate 52, there is a risk of uneven heating as in the conventional case, but since the transparent plate 51 is heated via silicon oil as a heating medium, Uneven heating with respect to the transparent plate 51 does not occur. Since the pressure in the gap 53 increases when the silicon oil is heated and expanded, it is desirable to provide the buffer tank 9 that leads to the gap 53.

本発明は上記した形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々の変更を加えてもかまわない。   The present invention is not limited to the embodiment described above, and various modifications may be made without departing from the scope of the present invention.
