Description

本考案は噴水装置、さらに詳しくは噴水のパターンを変えることが簡単にでき、噴水の駆動や照明手段の冷却を効率良く自然空冷或いは強制空冷ができてる噴水装置に関する。 The present invention relates to a fountain device, and more particularly, to a fountain device that can easily change the pattern of a fountain and that can efficiently perform natural air cooling or forced air cooling for driving the fountain and cooling the illumination means.

最近、池や水槽に噴水装置を取り付け水流を起こし水の浄化をしたり、濾過手段に格段の工夫をこらして水の交換をすくなくしたりと多種多様なものが市販されている。例えば文献１の特開平８−１１７６６１号１の号公報のように、出口の噴射口に至る通路の流路断面積を同じか又は漸次減少させて液体を薄膜状に噴射させるものや、特許文献６の特開２００３−４７８９１号公報のように、外方に広がる曲面形状の上部内壁を有する導管と、この導管の上部に配置される円板状の平板蓋とからなるカップリングで構成されたノズルてメロン形状の球体薄膜の噴射体があるが、ノズルに水草等のごみが詰まるものである。また、文献２の特開平８−２７３４０７号１の号公報のように、発光部が水で冷却されるものであり、そのメンテナンス等が面倒である。さらに、文献３の特開平９−７５８０８号公報のように、導水管の噴水口の端縁部から側方に延出する水誘導板と、噴水口の上方に水誘導板の表面から所定間隔をおいて設置されかつ水誘導板より径小の邪魔板と、この水誘導板の周縁部に立設された水流変更板とを有し、この水誘導板上を誘導された水流が水流変更板の上端縁部から空中に噴出させるものであるが、本考案のように噴水のパターンを変えることが簡単にでき、噴水の駆動や照明手段の冷却を効率良く自然空冷或いは強制空冷ができてる噴水装置ではない。さらには、特許文献４の特開２０００−２８８４４５号公報のものも、薄いリング状の水流を噴出する水流噴出部と、この水流噴出部へ所定の圧力をかけながら水を供給する給水部と、水流噴出部からの水を給水部へ循環させるための循環部からなるもので、上述のような本考案のように噴水のパターンを変えることが簡単にできものではないし、このものはろか装置や別のポンプが必要である。またさらに、特許文献５の特開２００１−７４号公報のように、水槽内に立設された揚水管と、この揚水管上端に固定円盤と、その上方に回転円盤とからなり水をらせん状の流路を通って固定円盤中心部から周縁部に向かって流れ、周縁から薄膜状に撒水させる撒水装置と、この水槽の上部に透明なフィルムからなる円錐台形の傘を設けたもので、本考案とは課題も構成もことなり、撒水装置の構造も複雑である。 Recently, a wide variety of products have been put on the market, such as installing a fountain device in a pond or aquarium to purify the water by purging water, or drastically devising the filtering means to eliminate water exchange. For example, as disclosed in Japanese Patent Application Laid-Open No. 8-117661 of Document 1, a liquid is ejected in the form of a thin film by reducing the channel cross-sectional area of the passage leading to the ejection port of the outlet to the same or gradually, or Patent Document As shown in Japanese Patent Application Laid-Open No. 2003-47891, it is constituted by a coupling comprising a conduit having an upper inner wall with a curved surface extending outward, and a disc-shaped flat plate lid disposed on the upper portion of the conduit. There is a melon-shaped spherical thin film sprayer as a nozzle, but the nozzle is clogged with garbage such as aquatic plants. In addition, as disclosed in Japanese Patent Application Laid-Open No. 8-273407 of Document 2, the light emitting unit is cooled with water, and its maintenance is troublesome. Further, as disclosed in Japanese Patent Laid-Open No. 9-75808 of Document 3, a water guide plate extending laterally from the edge of the fountain port of the water conduit, and a predetermined distance from the surface of the water guide plate above the fountain port A baffle plate that is smaller in diameter than the water guide plate and a water flow changing plate that is erected on the peripheral edge of the water guide plate, and the water flow guided on the water guide plate changes the water flow Although it is ejected into the air from the upper edge of the plate, it is easy to change the pattern of the fountain as in the present invention, and natural air cooling or forced air cooling can be efficiently performed for driving the fountain and cooling the illumination means. It is not a fountain device. Furthermore, the thing of Unexamined-Japanese-Patent No. 2000-288445 of patent document 4 also has a water flow ejection part which ejects a thin ring-shaped water flow, and a water supply part which supplies water while applying a predetermined pressure to this water flow ejection part, It consists of a circulation part for circulating water from the water flow ejection part to the water supply part, and it is not easy to change the pattern of the fountain as in the present invention as described above. A separate pump is required. Furthermore, as disclosed in Japanese Patent Application Laid-Open No. 2001-74 of Patent Document 5, the water is made up of a pumping pipe erected in the water tank, a fixed disk at the upper end of the pumping pipe, and a rotating disk above it. This is a watering device that flows from the center of the fixed disk through the flow path toward the peripheral part and irrigates in a thin film form from the peripheral part, and a frustoconical umbrella made of a transparent film at the top of the water tank. The idea is different from the problem and configuration, and the structure of the flooding device is also complicated.

本願の考案者は、種々な噴水装置を市場に提供してきたが、簡単に噴水のパターンを変えることができ、この噴出した水が回りの空気を冷却させることを利用し、噴水の駆動や照明手段の冷却を効率良く自然空冷或いは強制空冷ができてる噴水装置を提供できることを知見し得たものである。
