一般に、上部ろ過装置を用いた水槽においては、水槽上部の前側に照明装置を配置し、後ろ側に上部ろ過装置を配置している。照明装置から発生する熱は照明装置自体を高温にすると共に周囲の空気に伝播し、また、そのうちの一部は空気伝播や輻射熱により水槽内部の水に伝播される。   In general, in a water tank using an upper filtration device, a lighting device is arranged on the front side of the upper part of the water tank, and an upper filtration device is arranged on the rear side. The heat generated from the lighting device raises the temperature of the lighting device itself and propagates to the surrounding air, and part of the heat is propagated to the water in the water tank by air propagation and radiant heat.

特開２００３−１６９５６６号公報（特許文献１）に記載の照明付き水槽は、光源が光半導体であり、かつ光半導体が水槽を構成する壁材の外面に設けられている。この水槽においては、光半導体を冷却する管路が設けられており、管路の上端および下端が水槽内と連通されている。

JP 2003-169666 A

しかしながら、従来の方式では、照明装置を上部ろ過装置の下には置くことができないため、一般に販売されている上部ろ過装置を水槽の上部に配置すると、上部ろ過装置の直下は照明の光が不足して水草の育成が難しくなるという問題があった。また、照明装置自体が高温になることで、発光光量の低下やランプや電子部品の寿命の低下等をもたらすという問題があった。   However, in the conventional method, since the lighting device cannot be placed under the upper filtration device, when the upper filtration device sold in general is placed on the upper part of the aquarium, the illumination light is insufficient under the upper filtration device. Then, there was a problem that it was difficult to grow aquatic plants. Further, there has been a problem that the lighting device itself has a high temperature, resulting in a decrease in the amount of emitted light and a decrease in the lifetime of the lamp and electronic components.

また、特開２００３−１６９５６６号公報（特許文献１）に記載の照明付き水槽では、上部ろ過装置を水槽の上部に配置すると、上部ろ過装置の直下は照明を当てることができないという問題があった。   Moreover, in the water tank with illumination described in Japanese Patent Application Laid-Open No. 2003-169666 (Patent Document 1), when the upper filtration device is disposed on the upper portion of the water tank, there is a problem that the light directly below the upper filtration device cannot be illuminated. .

そこで、この発明の目的は、水槽に配置したときに直下への照明が可能であり、また、照明部が高温になることを防止することが可能な上部ろ過装置を提供することである。   Therefore, an object of the present invention is to provide an upper filtration device that can illuminate directly below when placed in a water tank and that can prevent the illumination unit from becoming hot.

この発明に従った上部ろ過装置は、ろ過部を有し、ろ過部に水を通過させるための水路と、光源として発光ダイオードを有し、発光ダイオードから発生する熱を水路内の水に伝導することができるように水路の下に配置された照明部とを備える。   The upper filtration device according to the present invention has a filtration unit, has a water channel for allowing water to pass through the filtration unit, and a light emitting diode as a light source, and conducts heat generated from the light emitting diode to water in the water channel. And an illuminating part arranged under the water channel.

このようにすることにより、上部ろ過装置を水槽に配置したときに直下への照明が可能であり、また、照明部が高温になることを防止することが可能な上部ろ過装置を提供することができる。   By doing in this way, when the upper filtration device is arranged in the water tank, it is possible to illuminate directly below, and to provide an upper filtration device capable of preventing the illumination unit from becoming high temperature. it can.

この発明に従った上部ろ過装置は、発光ダイオードから発生する熱を伝導するための第１の熱伝導部と、第１の熱伝導部に接触する、または、第１の熱伝導部から離れることができるように設けられ、水路内の水に熱を伝導するための第２の熱伝導部とをさらに備えることが好ましい。   The upper filtration device according to the present invention is in contact with or away from the first heat conducting part for conducting heat generated from the light emitting diode and the first heat conducting part. It is preferable to further include a second heat conducting portion that is provided so that heat can be conducted to the water in the water channel.

特開２００３−１６９５６６号公報（特許文献１）に記載されている照明付き水槽では、常に光半導体から発生した熱を水槽内の水で冷却するため、夏場等に水槽中の水温が上昇している場合にさらに水温が上昇して、水槽内の魚や水草にダメージを与えるという問題があった。   In the illuminated water tank described in Japanese Patent Application Laid-Open No. 2003-169666 (Patent Document 1), the heat generated from the optical semiconductor is always cooled by the water in the water tank. When the water temperature is higher, there is a problem that the water temperature further rises and damages fish and aquatic plants in the aquarium.

第１の熱伝導部と第２の熱伝導部とをさらに備え、水路内の水に熱を伝導するための第２の熱伝導部が第１の熱伝導部から離れることができるように設けられていることによって、たとえば、水温が低いときには発光ダイオードから発生する熱を水路内の水に伝導して発光ダイオードを冷却し、また、水温が高いときには発光ダイオードから発生する熱を水路内の水に伝導しないようにすることができる。   A first heat conducting part and a second heat conducting part are further provided, and provided so that the second heat conducting part for conducting heat to water in the water channel can be separated from the first heat conducting part. For example, when the water temperature is low, the heat generated from the light emitting diode is conducted to the water in the water channel to cool the light emitting diode, and when the water temperature is high, the heat generated from the light emitting diode is transferred to the water in the water channel. It is possible to prevent conduction.

このようにすることにより、水槽内の水温が必要以上に上昇することを防ぐことが可能となる。   By doing in this way, it becomes possible to prevent the water temperature in a water tank rising more than necessary.

この発明に従った上部ろ過装置は、発光ダイオードから発生する熱を伝導するための第３の熱伝導部と、第３の熱伝導部に接触する、または、第３の熱伝導部から離れることができるように設けられ、大気に熱を伝導するための第４の熱伝導部とをさらに備えることが好ましい。   The upper filtration device according to the present invention is in contact with or away from the third heat conducting unit for conducting heat generated from the light emitting diode, and the third heat conducting unit. It is preferable to further include a fourth heat conduction part that is provided so that heat can be conducted to the atmosphere.

このようにすることにより、発光ダイオードから発生する熱を水路内の水に伝導して発光ダイオードを冷却し水槽内の水を加熱するか、または、発光ダイオードから発生する熱を大気に伝導して発光ダイオードを冷却し水槽内の水の温度上昇を極力抑えるかを選択することが可能となる。   By doing so, the heat generated from the light emitting diode is conducted to the water in the water channel to cool the light emitting diode and heat the water in the water tank, or the heat generated from the light emitting diode is conducted to the atmosphere. It is possible to select whether to cool the light emitting diode and suppress the temperature rise of the water in the water tank as much as possible.

この発明に従った上部ろ過装置は、水路内を流れる水の温度を検知する水温検知手段を備え、水温検知手段によって検知された水の温度に応じて、第１の熱伝導部に第２の熱伝導部が接触し、かつ、第３の熱伝導部から第４の熱伝導部が離れる第１の切替位置と、第１の熱伝導部から第２の熱伝導部が離れ、かつ、第３の熱伝導部に第４の熱伝導部が接触する第２の切替位置と、第１の熱伝導部に第２の熱伝導部が接触し、かつ、第３の熱伝導部に第４の熱伝導部が接触する第３の切替位置とを切替えることが可能であるように構成されていることが好ましい。   The upper filtration device according to the present invention includes a water temperature detecting means for detecting the temperature of the water flowing in the water channel, and the second heat conducting unit has a second temperature according to the temperature of the water detected by the water temperature detecting means. A first switching position where the heat conduction unit is in contact and the fourth heat conduction unit is separated from the third heat conduction unit; a second heat conduction unit is separated from the first heat conduction unit; and The second heat conduction part is in contact with the third heat conduction part, the second heat conduction part is in contact with the first heat conduction part, and the fourth heat conduction part is in the fourth state. It is preferable to be configured so as to be able to switch to the third switching position with which the heat conducting portion contacts.

このようにすることにより、例えば、水温が低ければ、熱伝導部を第１の切替位置にして、発光ダイオードから発生する熱を水路を循環する水に伝導することによって発光ダイオードを冷却し、一方、水温が高ければ、熱伝導部を第２の切替位置にして、発光ダイオードから発生する熱を大気に伝導することによって発光ダイオードを冷却することができる。また、熱伝導部を第３の切替位置にすることによって、発光ダイオードから発生する熱を水路中の水と大気の両方に伝導して発光ダイオードを冷却することができる。さらに、このように水温に応じて発光ダイオードから発生する熱を水路中の水に伝導することによって水温を上昇させる補助のヒーター動作が可能となる。   By doing so, for example, if the water temperature is low, the heat conducting unit is set to the first switching position, and the heat generated from the light emitting diode is conducted to the water circulating in the water channel, thereby cooling the light emitting diode. If the water temperature is high, the light-emitting diode can be cooled by setting the heat conducting portion to the second switching position and conducting heat generated from the light-emitting diode to the atmosphere. In addition, by setting the heat conducting portion to the third switching position, heat generated from the light emitting diode can be conducted to both water and air in the water channel to cool the light emitting diode. Furthermore, an auxiliary heater operation for raising the water temperature by conducting heat generated from the light emitting diode according to the water temperature to the water in the water channel becomes possible.

この発明に従った上部ろ過装置は、周囲の大気の温度を検知する気温検知手段を備え、気温検知手段によって検知された大気の温度に応じて、第１の熱伝導部に第２の熱伝導部が接触し、かつ、第３の熱伝導部から第４の熱伝導部が離れる第１の切替位置と、第１の熱伝導部から第２の熱伝導部が離れ、かつ、第３の熱伝導部に第４の熱伝導部が接触する第２の切替位置と、第１の熱伝導部に第２の熱伝導部が接触し、かつ、第３の熱伝導部に第４の熱伝導部が接触する第３の切替位置とを切替えることが可能であるように構成されていることが好ましい。   The upper filtration device according to the present invention includes an air temperature detecting means for detecting the temperature of the surrounding air, and the second heat conduction is provided to the first heat conducting portion in accordance with the air temperature detected by the air temperature detecting means. A first switching position where the second heat conducting portion is separated from the third heat conducting portion, a second heat conducting portion is separated from the first heat conducting portion, and a third heat conducting portion is separated from the third heat conducting portion. A second switching position at which the fourth heat conduction unit contacts the heat conduction unit, a second heat conduction unit at the first heat conduction unit, and a fourth heat at the third heat conduction unit. It is preferable that the third switching position with which the conductive portion contacts can be switched.

このようにすることにより、例えば、気温が低ければ、熱伝導部を第１の切替位置にして、発光ダイオードから発生する熱を水路を循環する水に伝導することによって発光ダイオードを冷却し、発光ダイオードから発生する熱を周囲の大気に伝導しないようにする。一方、気温が高ければ、熱伝導部を第２の切替位置にして、発光ダイオードから発生する熱を大気に伝導することによって発光ダイオードを冷却し、水路を循環する水を発光ダイオードから発生する熱で加熱しないようにすることができる。また、熱伝導部を第３の切替位置にすることによって、発光ダイオードから発生する熱を水路中の水と大気の両方に伝導して発光ダイオードを冷却することができる。このように、気温に応じて発光ダイオードから発生する熱を水路中の水に伝導することによって水温を上昇させる補助のヒーター動作が可能となる。   In this way, for example, when the temperature is low, the heat conducting unit is set to the first switching position, and the heat generated from the light emitting diode is conducted to the water circulating in the water channel, thereby cooling the light emitting diode and emitting light. The heat generated from the diode is not conducted to the surrounding atmosphere. On the other hand, if the temperature is high, the heat conduction part is set to the second switching position, the heat generated from the light emitting diode is conducted to the atmosphere to cool the light emitting diode, and the heat generated from the light emitting diode is circulated through the water channel. It is possible not to heat with. In addition, by setting the heat conducting portion to the third switching position, heat generated from the light emitting diode can be conducted to both water and air in the water channel to cool the light emitting diode. In this way, it is possible to perform an auxiliary heater operation that raises the water temperature by conducting heat generated from the light emitting diode to the water in the water channel according to the air temperature.

この発明に従った上部ろ過装置は、照明部の温度を検知する照明部温度検知手段を備え、照明部温度検知手段によって検知された照明部の温度に応じて、第１の熱伝導部に第２の熱伝導部が接触し、かつ、第３の熱伝導部から第４の熱伝導部が離れる第１の切替位置と、第１の熱伝導部から第２の熱伝導部が離れ、かつ、第３の熱伝導部に第４の熱伝導部が接触する第２の切替位置と、第１の熱伝導部に第２の熱伝導部が接触し、かつ、第３の熱伝導部に第４の熱伝導部が接触する第３の切替位置とを切替えることが可能であるように構成されていることが好ましい。   The upper filtration device according to the present invention includes an illumination unit temperature detection unit that detects the temperature of the illumination unit, and the first heat conduction unit includes a first heat conduction unit according to the temperature of the illumination unit detected by the illumination unit temperature detection unit. A first switching position where the second heat conducting unit is in contact and the fourth heat conducting unit is separated from the third heat conducting unit, and the second heat conducting unit is separated from the first heat conducting unit, and , The second switching position where the fourth heat conducting part comes into contact with the third heat conducting part, the second heat conducting part comes into contact with the first heat conducting part, and the third heat conducting part comes into contact with the third heat conducting part. It is preferable to be configured to be able to switch the third switching position with which the fourth heat conducting unit comes into contact.

このようにすることにより、照明部の温度が所定の温度以上であれば、熱伝導部を第３の切替位置にすることによって照明部の発光ダイオードから発生する熱を水路中の水と大気の両方に伝導することによって発光ダイオードを冷却し、照明部の温度が異常に高温になるのを防止することができる。   In this way, if the temperature of the illumination unit is equal to or higher than a predetermined temperature, the heat generated from the light emitting diode of the illumination unit is generated between the water in the water channel and the atmosphere by setting the heat conducting unit to the third switching position. By conducting to both, the light emitting diode can be cooled, and the temperature of the illumination unit can be prevented from becoming abnormally high.

以上のように、この発明によれば、水槽に配置したときに直下への照明が可能であり、また、照明部が高温になることを防止することが可能な上部ろ過装置を提供することができる。   As described above, according to the present invention, it is possible to provide an upper filtration device that can illuminate directly when placed in a water tank and can prevent the illumination unit from becoming high temperature. it can.

以下、この発明の実施の形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、この発明の一つの実施の形態として、水槽の上部に配置された上部ろ過装置の全体を示す図である。   FIG. 1 is a diagram showing an entire upper filtration device disposed in the upper part of a water tank as one embodiment of the present invention.

図１に示すように、水槽１の上に設置される上部ろ過装置１００は、水路として本体ケース１０１と、本体カバー１０２と、ろ過部としてろ材１０３と、すのこ１０４と、給水パイプ１０５と、循環ポンプ１０６と、送水パイプ１０７と、排水パイプ１０８と、照明部としてＬＥＤ照明基板１０９とを備える。ろ材１０３と、すのこ１０４と、送水パイプ１０７は、本体ケース１０１の内部に配置されている。   As shown in FIG. 1, the upper filtration device 100 installed on the water tank 1 includes a main body case 101 as a water channel, a main body cover 102, a filter medium 103 as a filtration unit, a snowboard 104, a water supply pipe 105, and a circulation. A pump 106, a water supply pipe 107, a drain pipe 108, and an LED illumination board 109 as an illumination unit are provided. The filter medium 103, the saw 104, and the water supply pipe 107 are disposed inside the main body case 101.

図２は、ＬＥＤ照明基板の全体を示す断面図である。   FIG. 2 is a cross-sectional view showing the entire LED illumination board.

図２に示すように、ＬＥＤ照明基板１０９には、熱伝導性能の良い金属等の基板が用いられており、本発明の実施の形態においてはアルミニウム基板１１０が用いられている。アルミニウム基板１１０上には発光ダイオード（ＬＥＤ）１１１や電子部品が実装されており、防水のために透明シリコン１１２によってモールド加工が施されている。また、ＬＥＤ照明基板１０９は本体ケース１０１の下部である底面に配置されており、発光ダイオード１１１を実装した表面が水槽１の水面側に露出しており、発光ダイオード１１１を実装していないアルミニウム基板１１０の裏面が本体ケース１０１内において水が通過する部分に露出するように取り付けられている。   As shown in FIG. 2, the LED illumination substrate 109 is a substrate made of metal or the like having a good thermal conductivity, and an aluminum substrate 110 is used in the embodiment of the present invention. A light emitting diode (LED) 111 and electronic components are mounted on the aluminum substrate 110, and are molded with transparent silicon 112 for waterproofing. The LED illumination board 109 is disposed on the bottom surface, which is the lower part of the main body case 101, and the surface on which the light emitting diode 111 is mounted is exposed on the water surface side of the water tank 1, and the aluminum board on which the light emitting diode 111 is not mounted. The back surface of 110 is attached so as to be exposed at a portion through which water passes in the main body case 101.

循環ポンプ１０６の電源が入れられて循環ポンプ１０６が駆動すると、水槽１内の水は、給水パイプ１０５から吸引されて、循環ポンプ１０６と送水パイプ１０７を通って本体ケース１０１内に流入し、本体ケース１０１内でろ材１０３を通過することによってろ過され、すのこ１０４を通ってＬＥＤ照明基板１０９の裏面に接触するように流れ、排水パイプ１０８を通って水槽１内に戻るように循環する。   When the circulation pump 106 is turned on and the circulation pump 106 is driven, the water in the water tank 1 is sucked from the water supply pipe 105 and flows into the main body case 101 through the circulation pump 106 and the water supply pipe 107. It is filtered by passing through the filter medium 103 in the case 101, flows so as to come into contact with the back surface of the LED lighting substrate 109 through the slat 104, and circulates so as to return to the water tank 1 through the drain pipe 108.

ＬＥＤ照明基板１０９に通電されると発光ダイオード１１１が点灯し、本体ケース１０１の底面から下向きに水槽１の内部が照らされる。発光ダイオード１１１が点灯中に発光ダイオード１１１から発生する熱はＬＥＤ照明基板１０９に伝導され、ＬＥＤ照明基板１０９に伝導された熱はＬＥＤ照明基板１０９の背面を通過する循環水に伝導される。このようにして、ＬＥＤ照明基板１０９が冷却される。   When the LED illumination board 109 is energized, the light emitting diode 111 is turned on, and the inside of the water tank 1 is illuminated downward from the bottom surface of the main body case 101. The heat generated from the light emitting diode 111 while the light emitting diode 111 is turned on is conducted to the LED illumination board 109, and the heat conducted to the LED illumination board 109 is conducted to the circulating water passing through the back surface of the LED illumination board 109. In this way, the LED illumination board 109 is cooled.

このように、上部ろ過装置１００は、ろ材１０３を有し、ろ材１０３に水を通過させるための本体ケース１０１と、光源として発光ダイオード１１１を有し、発光ダイオード１１１から発生する熱を本体ケース１０１内の水に伝導することができるように配置されたＬＥＤ照明基板１０９とを備え、ＬＥＤ照明基板１０９は、本体ケース１０１の下部に配置されている。   As described above, the upper filtration device 100 includes the filter medium 103, the main body case 101 for allowing water to pass through the filter medium 103, and the light emitting diode 111 as a light source, and generates heat generated from the light emitting diode 111. The LED illumination board 109 is arranged so as to be able to conduct water to the inside, and the LED illumination board 109 is arranged below the main body case 101.

このようにすることにより、水槽１に配置したときに直下への照明が可能であり、また、ＬＥＤ照明基板１０９が高温になることを防止することが可能な上部ろ過装置１００を提供することができる。   By doing so, it is possible to provide an upper filtration device 100 that can illuminate directly when placed in the water tank 1 and can prevent the LED illumination board 109 from becoming high temperature. it can.

図３は、この発明のもう一つの実施の形態として、水槽の上部に配置された上部ろ過装置の全体を示す図である。   FIG. 3 is a diagram showing the entire upper filtration device disposed in the upper part of the water tank, as another embodiment of the present invention.

図３に示すように、水槽１の上に設置される上部ろ過装置２００は、上部ろ過装置１００と異なる点としては、第１の熱伝導部として循環水側熱伝導板２０１と、第２の熱伝導部として循環水側放熱板２０２と、循環水側放熱切替モーター２０３と、第３の熱伝導部として空気側熱伝導板２０４と、第４の熱伝導部として空気側放熱板２０５と、空気側放熱切替モーター２０６と、水温検知手段としてサーミスタ２０７とをさらに備える。   As shown in FIG. 3, the upper filtration device 200 installed on the water tank 1 is different from the upper filtration device 100 in that the circulating water-side heat conduction plate 201 and the second heat conduction unit 201 are used as the first heat conduction unit. Circulating water side heat radiating plate 202 as a heat conducting part, circulating water side heat radiating switching motor 203, air side heat conducting plate 204 as a third heat conducting part, air side heat radiating plate 205 as a fourth heat conducting part, An air-side heat radiation switching motor 206 and a thermistor 207 as water temperature detecting means are further provided.

また、上部ろ過装置２００が上部ろ過装置１００と異なる点として、ＬＥＤ照明基板１０９は、本体ケース１０１の底面に配置されており、発光ダイオード１１１を実装した表面が水槽１の水面側に露出しており、発光ダイオード１１１を実装していないＬＥＤ照明基板１０９の裏面が本体ケース１０１の底面外側に面するように取り付けられている。   Further, the upper filtration device 200 is different from the upper filtration device 100 in that the LED illumination board 109 is disposed on the bottom surface of the main body case 101, and the surface on which the light emitting diode 111 is mounted is exposed on the water surface side of the water tank 1. The LED illumination board 109 on which the light emitting diode 111 is not mounted is attached so that the back surface faces the outside of the bottom surface of the main body case 101.

上部ろ過装置２００のその他の構成は、上部ろ過装置１００と同様である。   Other configurations of the upper filtration device 200 are the same as those of the upper filtration device 100.

循環水側放熱板２０２は、本体ケース１０１の一方側の底面に配置されており、一方の面が水槽１の内部に貯められた水の水面側に露出しており、他方の面が本体ケース１０１の内部の循環水が通過する部分に露出するように取り付けられている。   The circulating water-side heat sink 202 is disposed on the bottom surface on one side of the main body case 101, one surface is exposed to the water surface side of the water stored in the water tank 1, and the other surface is the main body case. It is attached so that the circulating water inside 101 is exposed to the part through which it passes.

空気側放熱板２０５は、本体ケース１０１の外部において、循環水側放熱板２０２が配置される側と反対側の側面と底面に沿って配置されている。   The air side heat radiating plate 205 is disposed outside the main body case 101 along the side surface and the bottom surface opposite to the side where the circulating water side heat radiating plate 202 is disposed.

循環水側放熱切替モーター２０３は本体ケース１０１の底面のＬＥＤ照明基板１０９と循環水側放熱板２０２との間に配置されている。循環水側放熱切替モーター２０３を駆動することで循環水側熱伝導板２０１が回転して、循環水側熱伝導板２０１がＬＥＤ照明基板１０９と循環水側放熱板２０２の両方に接触する状態と、循環水側熱伝導板２０１がＬＥＤ照明基板１０９と循環水側放熱板２０２のどちらにも接触しない状態とを切り替えることができる。   The circulating water side heat radiation switching motor 203 is disposed between the LED illumination board 109 on the bottom surface of the main body case 101 and the circulating water side heat radiation plate 202. The circulating water side heat conduction plate 201 is rotated by driving the circulating water side heat radiation switching motor 203, and the circulating water side heat conduction plate 201 is in contact with both the LED illumination board 109 and the circulating water side heat radiation plate 202; The state in which the circulating water-side heat conduction plate 201 is not in contact with either the LED illumination board 109 or the circulating water-side heat radiating plate 202 can be switched.

このように、上部ろ過装置２００は、発光ダイオード１１１から発生する熱を伝導するための循環水側熱伝導板２０１と、循環水側熱伝導板２０１に接触する、または、循環水側熱伝導板２０１から離れることができるように設けられ、水路内の水に熱を伝導するための循環水側放熱板２０２とをさらに備える。   As described above, the upper filtration device 200 is in contact with the circulating water side heat conduction plate 201 and the circulating water side heat conduction plate 201 for conducting heat generated from the light emitting diode 111 or the circulating water side heat conduction plate. It is further provided with the circulating water side heat sink 202 provided so that it can leave | separate from 201, and conducts heat to the water in a water channel.

循環水側熱伝導板２０１と循環水側放熱板２０２とをさらに備え、水路内の水に熱を伝導するための循環水側放熱板２０２が循環水側熱伝導板２０１に接触する、または循環水側熱伝導板２０１から離れることができるように設けられていることによって、たとえば、水温が低いときには循環水側熱伝導板２０１がＬＥＤ照明基板１０９と循環水側放熱板２０２の両方に接触して発光ダイオード１１１から発生する熱を本体ケース１０１内の循環水に伝導して発光ダイオード１１１を冷却し、また、水温が高いときには、循環水側熱伝導板２０１がＬＥＤ照明基板１０９と循環水側放熱板２０２のどちらにも接触しないで発光ダイオード１１１から発生する熱を本体ケース１０１内の循環水に伝導しないようにすることができる。   The circulating water side heat conducting plate 201 and the circulating water side heat radiating plate 202 are further provided, and the circulating water side heat radiating plate 202 for conducting heat to the water in the water channel contacts the circulating water side heat conducting plate 201 or circulates. For example, when the water temperature is low, the circulating water side heat conducting plate 201 comes into contact with both the LED lighting board 109 and the circulating water side heat radiating plate 202 by being provided so as to be separated from the water side heat conducting plate 201. The heat generated from the light emitting diode 111 is conducted to the circulating water in the main body case 101 to cool the light emitting diode 111. When the water temperature is high, the circulating water side heat conduction plate 201 is connected to the LED illumination board 109 and the circulating water side. It is possible to prevent the heat generated from the light emitting diode 111 from being conducted to the circulating water in the main body case 101 without contacting any of the heat radiating plates 202.

このようにすることにより、水槽１内の水温が必要以上に上昇することを防ぐことが可能となる。   By doing in this way, it becomes possible to prevent the water temperature in the water tank 1 from rising more than necessary.

空気側放熱切替モーター２０６は本体ケース１０１の底面のＬＥＤ照明基板１０９と空気側放熱板２０５との間に配置されている。空気側放熱切替モーター２０６を駆動することで空気側熱伝導板２０４が回転して、空気側熱伝導板２０４がＬＥＤ照明基板１０９と空気側放熱板２０５の両方に接触する状態と、空気側熱伝導板２０４がＬＥＤ照明基板１０９と空気側放熱板２０５の両方に接触しない状態を切り替えることができる。   The air side heat radiation switching motor 206 is disposed between the LED illumination board 109 on the bottom surface of the main body case 101 and the air side heat radiation plate 205. Driving the air-side heat dissipation switching motor 206 causes the air-side heat conduction plate 204 to rotate, so that the air-side heat conduction plate 204 contacts both the LED lighting board 109 and the air-side heat dissipation plate 205, and the air-side heat The state where the conductive plate 204 is not in contact with both the LED lighting substrate 109 and the air-side heat radiating plate 205 can be switched.

このように、上部ろ過装置２００は、発光ダイオード１１１から発生する熱を伝導するための空気側熱伝導板２０４と、空気側熱伝導板２０４に接触する、または、空気側熱伝導板２０４から離れることができるように設けられ、大気に熱を伝導するための空気側放熱板２０５とをさらに備える。   As described above, the upper filtration device 200 is in contact with the air-side heat conduction plate 204 and the air-side heat conduction plate 204 for conducting heat generated from the light emitting diode 111, or is separated from the air-side heat conduction plate 204. And an air-side heat dissipating plate 205 for conducting heat to the atmosphere.

このようにすることにより、空気側熱伝導板２０４がＬＥＤ照明基板１０９と空気側放熱板２０５の両方に接触して発光ダイオード１１１から発生する熱を本体ケース１０１内の水に伝導して発光ダイオード１１１を冷却し水槽１内の水を加熱するか、または、空気側熱伝導板２０４がＬＥＤ照明基板１０９と空気側放熱板２０５のどちらにも接触しないで発光ダイオード１１１から発生する熱を大気に伝導して発光ダイオード１１１を冷却し水槽１内の水の温度上昇を極力抑えるかを選択することが可能となる。   By doing so, the air-side heat conducting plate 204 is in contact with both the LED lighting board 109 and the air-side heat radiating plate 205, and heat generated from the light emitting diode 111 is conducted to the water in the main body case 101 to emit light. 111 is cooled and the water in the water tank 1 is heated, or the air-side heat conduction plate 204 is not in contact with either the LED illumination board 109 or the air-side heat dissipation plate 205, and heat generated from the light emitting diode 111 is released to the atmosphere. It is possible to select whether to cool the light emitting diode 111 by conduction and suppress the temperature rise of the water in the water tank 1 as much as possible.

具体的には、ＬＥＤ照明基板１０９に通電されると発光ダイオード１１１が点灯し、本体ケース１０１の底面から水槽１の内部が照らされる。発光ダイオード１１１が点灯中に発生する熱はアルミニウム基板１１０に伝導する。このとき、循環水側放熱モーター２０３の駆動によって循環水側熱伝導板２０１がＬＥＤ照明基板１０９と循環水側放熱板２０２の両方に接触する状態となっている場合は、ＬＥＤ照明基板１０９に伝導した熱は循環水側熱伝導板２０１を介して循環水側放熱板２０２に伝導し、循環水側放熱板２０２に伝導した熱は循環水側放熱板２０２の上を通過する循環水に伝導することによって冷却される。また、空気側放熱モーター２０６の駆動によって空気側熱伝導板２０４がＬＥＤ照明基板１０９と空気側放熱板２０５の両方に接触する状態となっている場合は、ＬＥＤ照明基板１０９に伝導した熱は空気側熱伝導板２０４を介して空気側放熱板２０５に伝導し、空気側放熱板２０５に伝導した熱は水槽１の外部の空気によって冷却される。   Specifically, when the LED illumination board 109 is energized, the light emitting diode 111 is turned on, and the inside of the water tank 1 is illuminated from the bottom surface of the main body case 101. Heat generated while the light emitting diode 111 is turned on is conducted to the aluminum substrate 110. At this time, when the circulating water side heat conduction plate 201 is in contact with both the LED lighting board 109 and the circulating water side heat sink 202 by driving the circulating water side heat radiation motor 203, it is conducted to the LED lighting board 109. The conducted heat is conducted to the circulating water side heat radiating plate 202 through the circulating water side heat conducting plate 201, and the heat conducted to the circulating water side heat radiating plate 202 is conducted to the circulating water passing over the circulating water side heat radiating plate 202. Is cooled by. In addition, when the air-side heat conduction plate 204 is in contact with both the LED illumination board 109 and the air-side heat radiation board 205 by driving the air-side heat radiation motor 206, the heat conducted to the LED illumination board 109 is air. The heat conducted to the air side heat radiating plate 205 via the side heat conducting plate 204 and the heat conducted to the air side heat radiating plate 205 is cooled by the air outside the water tank 1.

上部ろ過装置３００は、循環水側放熱切替モーター２０３と空気側放熱切替モーター２０６の駆動と駆動停止とを切替えることによって、循環水側熱伝導板２０１に循環水側放熱板２０２が接触し、かつ、空気側熱伝導板２０４から空気側放熱板２０５が離れる第１の切替位置と、循環水側熱伝導板２０１から循環水側放熱板２０２が離れ、かつ、空気側熱伝導板２０４に空気側放熱板２０５が接触する第２の切替位置と、循環水側熱伝導板２０１に循環水側放熱板２０２が接触し、かつ、空気側熱伝導板２０４に空気側放熱板２０５が接触する第３の切替位置とを切替えることが可能であるように構成されている。   The upper filtration device 300 switches the circulating water side heat radiation switching motor 203 and the air side heat radiation switching motor 206 between driving and stopping, so that the circulating water side heat radiation plate 202 is in contact with the circulating water side heat conduction plate 201, and The first switching position where the air-side heat radiation plate 205 is separated from the air-side heat conduction plate 204, the circulating water-side heat radiation plate 202 is separated from the circulation water-side heat conduction plate 201, and the air-side heat conduction plate 204 is connected to the air side. A second switching position where the heat radiating plate 205 comes into contact, a third position where the circulating water side heat radiating plate 202 contacts the circulating water side heat conducting plate 201 and the air side heat radiating plate 205 contacts the air side heat conducting plate 204. These switching positions can be switched.

サーミスタ２０７は本体ケース１０１の内部の循環水が通過する部分に配置されて、循環水の温度を検知する。   The thermistor 207 is disposed in a portion through which the circulating water inside the main body case 101 passes, and detects the temperature of the circulating water.

図４は、発光ダイオードで発生した熱を循環水に伝導するときの上部ろ過装置の底面を示す図である。   FIG. 4 is a diagram illustrating a bottom surface of the upper filtration device when the heat generated in the light emitting diode is conducted to the circulating water.

図４に示すように、サーミスタ２０７で検知した温度が３０℃未満の場合には、循環水側放熱切替モーター２０３と空気側放熱切替モーター２０６の駆動によって、第１の切替位置にする。すなわち、循環水側熱伝導板２０１をＬＥＤ照明基板１０９と循環水側放熱板２０３の両方に接触する状態にすることで、発光ダイオード１１１で発生した熱を循環水に伝導して加熱し、空気側熱伝導板２０４をＬＥＤ照明基板１０９と空気側放熱板２０５の両方に接触しない状態にすることで、発光ダイオード１１１で発生した熱を水槽１外部の空気に伝導しないようにする。   As shown in FIG. 4, when the temperature detected by the thermistor 207 is less than 30 ° C., the first switching position is set by driving the circulating water side heat radiation switching motor 203 and the air side heat radiation switching motor 206. That is, by bringing the circulating water-side heat conduction plate 201 into contact with both the LED lighting substrate 109 and the circulating water-side heat radiating plate 203, the heat generated in the light emitting diode 111 is conducted to the circulating water and heated. By making the side heat conductive plate 204 not in contact with both the LED lighting substrate 109 and the air side heat radiating plate 205, the heat generated in the light emitting diode 111 is not conducted to the air outside the water tank 1.

図５は、発光ダイオードで発生した熱を大気に伝導するときの上部ろ過装置の底面を示す図である。   FIG. 5 is a diagram illustrating a bottom surface of the upper filtration device when the heat generated in the light emitting diode is conducted to the atmosphere.

図５に示すように、サーミスタ２０７で検知した温度が３０℃以上の場合には、循環水側放熱切替モーター２０３と空気側切替モーター２０５の駆動によって、第２の切替位置にする。すなわち、循環水側熱伝導板２０１をＬＥＤ照明基板１０９と循環水側放熱板２０２の両方に接触しない状態にすることで、循環水の加熱を行わないようにし、空気側熱伝導板２０４をＬＥＤ照明基板１０９と空気側放熱板２０５の両方に接触する状態にすることで、水槽１の外部の空気に熱を伝導して冷却する。   As shown in FIG. 5, when the temperature detected by the thermistor 207 is 30 ° C. or higher, the second switching position is set by driving the circulating water side heat radiation switching motor 203 and the air side switching motor 205. In other words, the circulating water side heat conduction plate 201 is not in contact with both the LED illumination board 109 and the circulating water side heat radiating plate 202 so that the circulating water is not heated, and the air side heat conduction plate 204 is connected to the LED. By bringing the lighting substrate 109 and the air-side heat sink 205 into contact with each other, heat is conducted to the air outside the water tank 1 to cool it.

このように、上部ろ過装置３００は、本体ケース１０１内を流れる水の温度を検知するサーミスタ２０７を備え、サーミスタ２０７によって検知された水の温度に応じて、循環水側熱伝導板２０１に循環水側放熱板２０２が接触し、かつ、空気側熱伝導板２０４から空気側放熱板２０５が離れる第１の切替位置と、循環水側熱伝導板２０１から循環水側放熱板２０２が離れ、かつ、空気側熱伝導板２０４に空気側放熱板２０５が接触する第２の切替位置と、循環水側熱伝導板２０１に循環水側放熱板２０２が接触し、かつ、空気側熱伝導板２０４に空気側放熱板２０５が接触する第３の切替位置とを切替えることが可能であるように構成されている。   Thus, the upper filtration device 300 includes the thermistor 207 that detects the temperature of the water flowing in the main body case 101, and the circulating water is supplied to the circulating water-side heat conduction plate 201 according to the temperature of the water detected by the thermistor 207. A first switching position where the side heat radiating plate 202 contacts and the air side heat radiating plate 205 is separated from the air side heat conducting plate 204, the circulating water side radiating plate 202 is separated from the circulating water side heat conducting plate 201, and The second switching position where the air side heat radiating plate 205 contacts the air side heat conducting plate 204, the circulating water side heat radiating plate 202 contacts the circulating water side heat conducting plate 201, and the air side heat conducting plate 204 is air The third switching position with which the side heat radiating plate 205 is in contact can be switched.

このようにすることにより、例えば、水温が低ければ、第１の切替位置にして、発光ダイオード１１１から発生する熱を本体ケース１０１を循環する水に伝導することによって発光ダイオード１１１を冷却し、一方、水温が高ければ、第２の切替位置にして、発光ダイオード１１１から発生する熱を大気に伝導することによって発光ダイオード１１１を冷却することができる。また、第３の切替位置にすることによって、発光ダイオード１１１から発生する熱を本体ケース１０１中の水と大気の両方に伝導して発光ダイオード１１１を冷却することができる。さらに、水温に応じて発光ダイオード１１１から発生する熱を本体ケース１０１中の水に伝導することによって水温を上昇させる補助のヒーター動作が可能となる。   In this way, for example, if the water temperature is low, the light emitting diode 111 is cooled by conducting heat generated from the light emitting diode 111 to the water circulating through the main body case 101 at the first switching position. If the water temperature is high, the light emitting diode 111 can be cooled by conducting heat generated from the light emitting diode 111 to the atmosphere at the second switching position. Further, by setting the third switching position, the heat generated from the light emitting diode 111 can be conducted to both the water and the atmosphere in the main body case 101 to cool the light emitting diode 111. Further, an auxiliary heater operation for raising the water temperature by conducting heat generated from the light emitting diode 111 to the water in the main body case 101 according to the water temperature is possible.

図６は、この発明のさらにもう一つの実施の形態として、水槽の上部に配置された上部ろ過装置の全体を示す図である。   FIG. 6 is a diagram showing the entire upper filtration device arranged at the upper part of the water tank, as yet another embodiment of the present invention.

図６に示すように、水槽１の上に設置される上部ろ過装置３００は、上部ろ過装置２００と異なる点として、照明部温度検出手段としてＬＥＤ基板サーミスタ３０１と、気温検知手段として外部サーミスタ３０２をさらに備える。   As shown in FIG. 6, the upper filtration device 300 installed on the water tank 1 is different from the upper filtration device 200 in that an LED substrate thermistor 301 is used as the illumination unit temperature detection means, and an external thermistor 302 is used as the temperature detection means. Further prepare.

上部ろ過装置３００のその他の構成は、上部ろ過装置２００と同様である。   Other configurations of the upper filtration device 300 are the same as those of the upper filtration device 200.

外部サーミスタ３０２は、本体ケース１０１の外側に配置されて、水槽周辺の温度を検知する。ＬＥＤ基板サーミスタ３０１は、ＬＥＤ照明基板１０９に密着して配置されて、ＬＥＤ照明基板１０９の温度を検知する。   The external thermistor 302 is disposed outside the main body case 101 and detects the temperature around the water tank. The LED substrate thermistor 301 is disposed in close contact with the LED illumination substrate 109 and detects the temperature of the LED illumination substrate 109.

図７は、発光ダイオードにおいて発生した熱を、大気には伝導せず、循環水に伝導するときの上部ろ過装置の底面を示す図である。   FIG. 7 is a view showing the bottom surface of the upper filtration device when the heat generated in the light emitting diode is not conducted to the atmosphere but is conducted to the circulating water.

図７に示すように、外部サーミスタ３０２で検知した温度が２８℃未満の場合には、循環水側放熱切替モーター２０３と空気側放熱切替モーター２０６の駆動によって第１の切替位置、すなわち、循環水側熱伝導板２０１をＬＥＤ照明基板１０９と循環水側放熱板２０２の両方に接触する状態にすることで、発光ダイオード１１１で発生した熱を循環水に伝導して循環水を加熱し、空気側熱伝導板２０４をＬＥＤ照明基板１０９と空気側放熱板１０５の両方に接触しない状態にすることで、発光ダイオード１１１で発生した熱を水槽１の外部の空気に伝導しないようにする。   As shown in FIG. 7, when the temperature detected by the external thermistor 302 is less than 28 ° C., the first switching position, that is, the circulating water is driven by driving the circulating water side heat radiation switching motor 203 and the air side heat radiation switching motor 206. By bringing the side heat conductive plate 201 into contact with both the LED lighting board 109 and the circulating water side heat radiating plate 202, the heat generated in the light emitting diode 111 is conducted to the circulating water to heat the circulating water, and the air side The heat conduction plate 204 is not in contact with both the LED lighting substrate 109 and the air-side heat radiation plate 105, so that the heat generated in the light emitting diode 111 is not conducted to the air outside the water tank 1.

図８は、発光ダイオードにおいて発生した熱を、循環水には伝導せず、大気に伝導するときの上部ろ過装置の底面を示す図である。   FIG. 8 is a view showing the bottom of the upper filtration device when the heat generated in the light emitting diode is not conducted to the circulating water but to the atmosphere.

図８に示すように、外部サーミスタ３０２で検知した温度が２８℃以上の場合には、循環水側放熱切替モーター２０３と空気側放熱切替モーター２０６の駆動によって循環水側熱伝導板２０１をＬＥＤ照明基板１０９と循環水側放熱板２０２の両方に接触しない状態にすることで、循環水への加熱を行わないようにし、空気側熱伝導板２０４をＬＥＤ照明基板１０９と空気側放熱板２０５の両方に接触する状態にすることで、水槽１の外部の空気に熱を伝導して冷却する。   As shown in FIG. 8, when the temperature detected by the external thermistor 302 is 28 ° C. or higher, the circulating water side heat conduction plate 201 is driven by LED lighting by driving the circulating water side heat radiation switching motor 203 and the air side heat radiation switching motor 206. By avoiding contact with both the substrate 109 and the circulating water side radiator plate 202, heating to the circulating water is prevented, and the air side heat conducting plate 204 is replaced with both the LED lighting substrate 109 and the air side radiator plate 205. By bringing the state into contact with the water, heat is conducted to the air outside the water tank 1 to cool it.

このように、上部ろ過装置３００は、周囲の大気の温度を検知する外部サーミスタ３０２を備え、外部サーミスタ３０２によって検知された大気の温度に応じて、循環水側熱伝導板２０１に循環水側放熱板２０２が接触し、かつ、空気側熱伝導板２０４から空気側放熱板２０５が離れる第１の切替位置と、循環水側熱伝導板２０１から循環水側放熱板２０２が離れ、かつ、空気側熱伝導板２０４に空気側放熱板２０５が接触する第２の切替位置と、循環水側熱伝導板２０１に循環水側放熱板２０２が接触し、かつ、空気側熱伝導板２０４に空気側放熱板２０５が接触する第３の切替位置とを切替えることが可能であるように構成されている。   As described above, the upper filtration device 300 includes the external thermistor 302 that detects the temperature of the surrounding atmosphere, and the circulating water-side heat release to the circulating water-side heat conduction plate 201 according to the temperature of the atmosphere detected by the external thermistor 302. The first switching position where the plate 202 is in contact and the air-side heat dissipating plate 205 is separated from the air-side heat conducting plate 204; the circulating water-side heat dissipating plate 202 is separated from the circulating water-side heat conducting plate 201; A second switching position where the air-side heat dissipation plate 205 is in contact with the heat conduction plate 204, the circulating water-side heat dissipation plate 202 is in contact with the circulating water-side heat conduction plate 201, and the air-side heat dissipation is performed in the air-side heat conduction plate 204. The third switching position with which the plate 205 is in contact can be switched.

このようにすることにより、例えば、気温が低ければ、第１の切替位置にして、発光ダイオード１１１から発生する熱を本体ケース１０１を循環する水に伝導することによって発光ダイオード１１１を冷却し、発光ダイオード１１１で発生した熱を水槽１の外部の空気に伝導しないようにすることができる。一方、気温が高ければ、第２の切替位置にして、発光ダイオード１１１から発生する熱を大気に伝導することによって発光ダイオード１１１を冷却し、循環水への加熱を行わないようにすることができる。また、第３の切替位置にすることによって、発光ダイオード１１１から発生する熱を本体ケース１０１中の水と大気の両方に伝導して発光ダイオード１１１を冷却することができる。さらに、このように気温に応じて発光ダイオード１１１から発生する熱を本体ケース１０１中の水に伝導することによって水温を上昇させる補助のヒーター動作が可能となる。   In this way, for example, when the temperature is low, the light emitting diode 111 is cooled by transmitting heat generated from the light emitting diode 111 to the water circulating in the main body case 101 at the first switching position. It is possible to prevent the heat generated in the diode 111 from being conducted to the air outside the water tank 1. On the other hand, if the temperature is high, the second switching position can be used to cool the light emitting diode 111 by conducting heat generated from the light emitting diode 111 to the atmosphere, so that heating to the circulating water is not performed. . Further, by setting the third switching position, the heat generated from the light emitting diode 111 can be conducted to both the water and the atmosphere in the main body case 101 to cool the light emitting diode 111. Furthermore, an auxiliary heater operation for increasing the water temperature by conducting the heat generated from the light emitting diode 111 according to the air temperature to the water in the main body case 101 is possible.

図９は、発光ダイオードにおいて発生した熱を循環水と大気の両方に伝導するときの上部ろ過装置の底面を示す図である。   FIG. 9 is a diagram showing the bottom surface of the upper filtration device when the heat generated in the light emitting diode is conducted to both circulating water and the atmosphere.

図９に示すように、ＬＥＤ基板サーミスタ３０１で検知したＬＥＤ照明基板１０９の温度が６０℃以上の場合には、外部サーミスタ３０２で検知した温度に関係なく、循環水側放熱切替モーター２０３と空気側放熱切替モーター２０６の駆動によって第３の切替位置、すなわち、循環水側熱伝導板２０１をＬＥＤ照明基板１０９と循環水側放熱板２０２の両方に接触する状態にすることで、発光ダイオード１１１で発生した熱を循環水に伝導して冷却すると共に、空気側熱伝導板２０４をＬＥＤ照明基板１０９と空気側放熱板２０５の両方に接触する状態にすることで、水槽１の外部の空気に熱を伝導して冷却する。   As shown in FIG. 9, when the temperature of the LED illumination board 109 detected by the LED board thermistor 301 is 60 ° C. or higher, the circulating water side heat radiation switching motor 203 and the air side are independent of the temperature detected by the external thermistor 302. Generated in the light emitting diode 111 by driving the heat dissipation switching motor 206 to bring the third switching position, that is, the circulating water side heat conduction plate 201 into contact with both the LED illumination board 109 and the circulating water side heat dissipation plate 202. The conducted heat is conducted to the circulating water for cooling, and the air-side heat conducting plate 204 is brought into contact with both the LED lighting board 109 and the air-side heat radiating plate 205, so that heat is applied to the air outside the water tank 1. Conducted and cooled.

このように、上部ろ過装置３００は、発光ダイオード１１１の温度を検知するＬＥＤ基板サーミスタ３０１を備え、ＬＥＤ基板サーミスタ３０１によって検知された水の温度に応じて、循環水側熱伝導板２０１に循環水側放熱板２０２が接触し、かつ、空気側熱伝導板２０４から空気側放熱板２０５が離れる第１の切替位置と、循環水側熱伝導板２０１から循環水側放熱板２０２が離れ、かつ、空気側熱伝導板２０４に空気側放熱板２０５が接触する第２の切替位置と、循環水側熱伝導板２０１に循環水側放熱板２０２が接触し、かつ、空気側熱伝導板２０４に空気側放熱板２０５が接触する第３の切替位置とを切替えることが可能であるように構成されている。   As described above, the upper filtration device 300 includes the LED substrate thermistor 301 that detects the temperature of the light emitting diode 111, and the circulating water is supplied to the circulating water-side heat conduction plate 201 according to the temperature of the water detected by the LED substrate thermistor 301. A first switching position where the side heat radiating plate 202 contacts and the air side heat radiating plate 205 is separated from the air side heat conducting plate 204, the circulating water side radiating plate 202 is separated from the circulating water side heat conducting plate 201, and The second switching position where the air side heat radiating plate 205 contacts the air side heat conducting plate 204, the circulating water side heat radiating plate 202 contacts the circulating water side heat conducting plate 201, and the air side heat conducting plate 204 is air The third switching position with which the side heat radiating plate 205 is in contact can be switched.
