Japanese Utility Model Publication No. 5-70267

現在この種のヒータ装置で最も小型の市販品は、容量１０リットル以下の観賞魚用水槽に使用するもので、電熱ヒータの定格消費電力が３０Ｗ、ガラス管やセミックス管で成る外装ケースの長さが約１５ｃｍ程度となっている。 Currently, the smallest commercial product of this type of heater device is used for aquarium fish with a capacity of 10 liters or less. The rated power consumption of the electric heater is 30 W, and the length of the outer case made of glass tubes or semimix tubes Is about 15 cm.

ところで、最近は、ネオンテトラ、グッピー、メダカ等の小型観賞魚を気軽に飼育することができるコンパクトサイズの水槽が市販されており、当該水槽は、その容量が５リットル以下で、縦・横・高さが１７×１７×１７ｃｍ以下と非常に小さく、本棚、飾り棚、各種キャビネット、テーブル、机等の片隅にも置けることから大変な人気を博している。 By the way, recently, compact-sized aquariums that can easily raise small ornamental fish such as neon tetra, guppy, and medaka have been marketed. It is very small as 17x17x17cm or less, and it is very popular because it can be placed in one corner of bookshelves, display racks, various cabinets, tables, desks, etc.

The electric heater and the temperature sensor are formed to have a length that can accommodate the longer one, and the electric heater and the temperature sensor face each other in parallel with a certain interval in the width direction of the case. It is arranged so that it may be arranged.

本考案によれば、観賞魚用水槽の槽内に設置する外装ケースの長さが従来に比べて大幅に短縮されるので、容量５リットル以下の超小型水槽にも最適な小型のヒータ装置を提供することができる。 According to the present invention, the length of the exterior case installed in the tank for the aquarium fish is greatly reduced compared to the conventional case, so a small heater device that is optimal for ultra-small water tanks with a capacity of 5 liters or less is also provided. Can be provided.

本考案の最良の実施形態は、観賞魚用水槽の槽内に設置する外装ケースが、その内部に配設する電熱ヒータと温度センサのいずれか全長の長い方を収容できる程度の長さに形成されると共に、電熱ヒータと温度センサとが該ケースの幅方向に一定の間隔をあけて並行に対峙するように配設された自動温度調節器付きの観賞魚用ヒータ装置である。 In the best mode of the present invention, the exterior case installed in the tank of the ornamental fish tank is formed to a length that can accommodate either the electric heater or the temperature sensor disposed in the inside of the tank. In addition, this is an ornamental fish heater device with an automatic temperature controller in which an electric heater and a temperature sensor are arranged so as to face each other in parallel in a width direction of the case.

そして、その外装ケースは、一般に自己消火性樹脂と称する難燃性プラスチックで成形された角トレイ形のケース本体とその蓋体とで形成され、ケース本体の内部には、電熱ヒータと温度センサとを並行に対峙させて固定するリブが形成されると共に、電気絶縁性を有する防水用シーリング剤が充填され、蓋体には、観賞魚用水槽の槽壁に吸着させるキスゴムと称する吸盤が取り付けられている。 The exterior case is formed of a square tray-shaped case body formed of a flame-retardant plastic generally called a self-extinguishing resin and its lid, and an electric heater, a temperature sensor, Ribs that are fixed in parallel with each other are formed, and a waterproof sealing agent having electrical insulation is filled, and a sucker called a kiss rubber that is adsorbed to the tank wall of the aquarium fish tank is attached to the lid. ing.

また、外装ケースの内部に配設する電熱ヒータは、巻き線抵抗器のパッケージをセラミックスケースとセメントで封じた角型セメント抵抗器で成り、特に容量５リットル以下の超小型水槽に用いるヒータ装置とする場合は、その電熱ヒータとして定格消費電力１０Ｗ〜２０Ｗの角型セメント抵抗器が用いられている。 The electric heater disposed inside the outer case is a square cement resistor in which a package of a winding resistor is sealed with a ceramic case and cement, and in particular, a heater device used for an ultra-small water tank having a capacity of 5 liters or less, When doing so, a square cement resistor having a rated power consumption of 10 W to 20 W is used as the electric heater.

図１は本考案に係る観賞魚用ヒータ装置の一例を示す平面図、図２はそのヒータ装置の外装ケースのケース本体にかぶせる蓋体の平面図、図３はそのヒータ装置の断面図である。 FIG. 1 is a plan view showing an example of an ornamental fish heater device according to the present invention, FIG. 2 is a plan view of a lid body that covers an outer case of the heater device, and FIG. 3 is a sectional view of the heater device. .

本例のヒータ装置は、観賞魚用水槽の槽内に設置する外装ケース１に電源コード２が取り付けられると共に、その外装ケース１の内部に、電源コード２の配線３に対して直列に接続された電熱ヒータ４と温度センサ５とが配設された自動温度調節器付きのヒータ装置であって、電熱ヒータ４は、温度センサ５よりも全長が長い定格消費電力１０Ｗ〜２０Ｗの角型セメント抵抗器で形成され、外装ケース１は、角型セメント抵抗器で成る電熱ヒータ４を収容できる程度の長さに形成されて、電熱ヒータ４と温度センサ５とが、外装ケース１の幅方向に一定の間隔をあけて並行に対峙するように設置されている。 In the heater device of this example, the power cord 2 is attached to the outer case 1 installed in the tank of the ornamental fish tank, and is connected in series to the wiring 3 of the power cord 2 inside the outer case 1. A heater device with an automatic temperature controller in which an electric heater 4 and a temperature sensor 5 are disposed. The electric heater 4 has a square cement resistance having a rated power consumption of 10 W to 20 W, which is longer than the temperature sensor 5. The outer case 1 is formed to a length that can accommodate the electric heater 4 made of a square cement resistor, and the electric heater 4 and the temperature sensor 5 are constant in the width direction of the outer case 1. It is installed so as to confront each other in parallel.

また、外装ケース１は、一般に自己消火性樹脂と称するＡＢＳ樹脂系等の難燃性プラスチックで成形された角トレイ形のケース本体６とその蓋体７とで形成されている。そして、ケース本体６の内部には、電熱ヒータ４と温度センサ５とを互いに並行に対峙させて固定するトラック形の環状リブ８が形成されると共に、電熱ヒータ４及び温度センサ５と電源コード２の配線３等を覆うように電気絶縁性を有する防水用シーリング剤１２が充填され、蓋体７には、観賞魚用水槽の槽壁に吸着させる一対の吸盤９、９が長さ方向に一定の間隔をあけて取り付けられている。 The exterior case 1 is formed of a square tray-shaped case body 6 and a lid 7 formed of a flame-retardant plastic such as an ABS resin generally called a self-extinguishing resin. A track-shaped annular rib 8 for fixing the electric heater 4 and the temperature sensor 5 to face each other in parallel is formed inside the case body 6, and the electric heater 4, the temperature sensor 5, and the power cord 2. A waterproof sealing agent 12 having electrical insulation is filled so as to cover the wiring 3 and the like, and a pair of suction cups 9, 9 to be adsorbed to the tank wall of the aquarium fish tank are fixed in the length direction on the lid body 7. It is attached with an interval of.

蓋体７は、これをケース本体６にかぶせたときに該ケース本体６に形成された環状リブ８の内側に納まる部分に、吸盤９、９を嵌め止めるスリット１０が形成されると共に、該スリット１０の中央部に、吸盤９の後端部を嵌め入れる穴１１が形成されて、該穴１１に後端部を嵌め入れた吸盤９、９をスリット１０の両端側に摺り動かして図２の如く取り付けるようになっている。そして、吸盤９、９が取り付けられた蓋体７をケース本体６にかぶせる際に、ケース本体６の周縁部に形成されたフック形の嵌合用リブ１３、１３…を蓋体７の周縁部に形成されたリブ受け部１４、１４…に嵌合させることにより、ケース本体６とこれにかぶせる蓋体７とを分離不能に一体化させて、外装ケース１の組立が完了する。 The lid body 7 is formed with a slit 10 for fitting the suction cups 9 and 9 into a portion that fits inside the annular rib 8 formed in the case body 6 when the lid body 7 is put on the case body 6. A hole 11 for fitting the rear end portion of the suction cup 9 is formed in the center of the suction cup 9, and the suction cups 9, 9 having the rear end portion fitted in the hole 11 are slid to both ends of the slit 10 as shown in FIG. It is designed to be attached as follows. And when covering the case body 6 with the cover body 7 to which the suction cups 9 and 9 are attached, hook-shaped fitting ribs 13 formed on the periphery of the case body 6 are provided on the periphery of the cover body 7. By fitting the formed rib receiving portions 14, 14..., The case main body 6 and the lid body 7 covering the case main body 6 are integrated so as not to be separated, and the assembly of the outer case 1 is completed.

以上のように、外装ケース１は、電熱ヒータ４と温度センサ５とを一定の間隔をあけて並行に対峙するように配設するため、従来のものに比べて幅広となるが、該ケース１の長さは、電熱ヒータ４を収容可能な程度の長さしかないので、少なくとも温度センサ５の長さ分だけは従来のものより短くなり、例えば定格消費電力１０Ｗの角型セメント抵抗器で成る電熱ヒータ４を収容可能な外装ケース１の長さは、約７ｃｍ前後で足りるから、容量が５リットル以下、縦・横・高さが１７×１７×１７ｃｍ以下の超小型水槽にも容易に設置することができる。 As described above, the outer case 1 is wider than the conventional case because the electric heater 4 and the temperature sensor 5 are arranged so as to face each other with a certain distance therebetween. Is only long enough to accommodate the electric heater 4, so that at least the length of the temperature sensor 5 is shorter than that of the conventional one, and is composed of, for example, a square cement resistor with a rated power consumption of 10 W. The length of the outer case 1 that can accommodate the electric heater 4 is about 7 cm, so it can be easily installed in ultra-small water tanks with a capacity of 5 liters or less and a height, width, and height of 17 x 17 x 17 cm or less. can do.

また、容量５リットル以下の観賞魚用水槽の水温を適温に保持するには、定格消費電力１０Ｗ程度の電熱ヒータ４で十分であり、また、電熱ヒータ４として安価で取付が簡単な既製の角型セメント抵抗器を用いれば、ヒータ装置全体の製造コストを大幅に低減することができる。また、ガラス管やセラミック管で成る従来の外装ケースは、床の上に落とすなどして破損するおそれがあったが、本例の如く外装ケース１を耐衝撃性に優れたＡＢＳ樹脂系の難燃性プラスチックで成形すれば、破損のおそれはなく、安全性も高い。更に、外装ケース1は、ケース本体６内に電熱ヒータ４と温度センサ５を配設し、防水用シーリング剤１２を充填して、該ケース本体６に蓋７をかぶせるだけで組立が完成するので、その組立加工コストも著しく低減される。したがって、本例のヒータ装置は、容量５リットル以下の安価な小型水槽に見合った低価格で販売することができる。 Moreover, in order to keep the water temperature of the ornamental fish tank with a capacity of 5 liters or less at an appropriate temperature, the electric heater 4 with a rated power consumption of about 10 W is sufficient, and the electric heater 4 is a ready-made corner that is inexpensive and easy to install. If a type | mold cement resistor is used, the manufacturing cost of the whole heater apparatus can be reduced significantly. In addition, the conventional exterior case made of a glass tube or a ceramic tube may be damaged by dropping it on the floor. However, as in this example, the exterior case 1 is difficult to be made of an ABS resin system having excellent impact resistance. If it is molded from flammable plastic, there is no risk of damage and safety is high. Furthermore, the exterior case 1 is assembled by simply placing the electric heater 4 and the temperature sensor 5 in the case body 6, filling the waterproof sealant 12, and covering the case body 6 with the lid 7. The assembly processing cost is also significantly reduced. Therefore, the heater device of this example can be sold at a low price corresponding to an inexpensive small water tank having a capacity of 5 liters or less.

本考案は、ネオンテトラ、グッピー、メダカ等の小型観賞魚を気軽に飼育することができる５リットル以下のコンパクトな観賞魚用水槽に最適なヒータ装置を提供することができる。 INDUSTRIAL APPLICABILITY The present invention can provide a heater device optimal for a small aquarium fish tank of 5 liters or less that can easily breed small aquarium fish such as neon tetra, guppy, and medaka.
