この考案は、自然に近いメカニズムで雪を生威し、降雪
させることができるようにした人工降雪装置に関する。[Detailed description of the invention] This invention relates to an artificial snow-making device that can generate and make snow by a mechanism close to nature.
この種人工降雪装置の従来のものは、低温室の天井に配
設したノズルから霧を発生させ、この霧を降下途中にお
いて氷結させて降雪させるようにしである。Conventional artificial snow-making devices of this kind generate fog from a nozzle placed on the ceiling of a low-temperature room, and freeze this fog on its way down to form snow.
しかしこのような人工降雪装置では、降下する雪は粒子
径の小なるものであって、静に降り積もる自然の雪とは
程遠いものである。However, in such an artificial snow-making device, the snow that falls has a small particle size, and is far from natural snow that falls quietly.

態の雪を降らせることができるようにした人工降雪装置
に関し、以下実施例図に基いて本考案を詳述する。This invention allows the artificially created ice crystals to expand and grow by extending the residence time in which they float together with the mist from the ultrasonic humidifier. Regarding an artificial snow-making device that can make snow fall, the present invention will be described in detail below based on embodiment figures.
図において、符号1は雪発生室を示し、この室は降雪室
2の上部に設けられている。In the figure, reference numeral 1 indicates a snow generating chamber, and this chamber is provided above the snow generating chamber 2.
雪発生室1内には、上下が開口し、かつ上部はど拡径す
る上部がり筒体よりなる浮遊室7を設けてあって、この
浮遊室の上部には網とか粗目の布などの多孔物よりなる
雪捕捉体7aを張設してあり、この捕捉体の上面に、回
転とか摺動をして雪を掻き落すためのスクレーパ8を設
けである。Inside the snow generation chamber 1, a floating chamber 7 is provided, which is made of a cylindrical body with an open top and bottom and an enlarged diameter at the top. A snow catching body 7a made of a material is stretched, and a scraper 8 for scraping off snow by rotating or sliding is provided on the upper surface of this snow catching body.
しかして雪発生室1内には、冷却た空気を浮遊室内へ下
部開口部から送り込むための冷却器5と送風機6を設け
であるとともに浮遊室内へ霧を供給する超音波加湿器3
を設けである。The snow generating chamber 1 is equipped with a cooler 5 and a blower 6 for sending cooled air into the floating chamber from the lower opening, and an ultrasonic humidifier 3 for supplying mist into the floating chamber.
This is provided.
また浮遊室内には、浮遊室内の霧へ断熱膨張した空気を
パルス的に噴出せしめる氷晶発生器のエアジェツトノズ
ル4を配設してあり、氷晶発生器は、先端に前記ノズル
4を有する給気管4aを、パルス信号によって瞬時開く
電磁弁9を介して圧縮機10に接続たものとしである。Furthermore, an air jet nozzle 4 of an ice crystal generator is disposed in the floating chamber to eject adiabatically expanded air into the mist in the floating chamber in pulses, and the ice crystal generator has the nozzle 4 at the tip. The air supply pipe 4a is connected to the compressor 10 via a solenoid valve 9 that opens instantaneously in response to a pulse signal.
超音波加湿器3には種々のものがあるが、例えば第2図
のごとく、ケーシング3a内に送風機3b1発振回路3
cを備え、かつ仕切板3dにて画された水槽3e内の水
3fの中に振動子3gが配せられ、水槽の上部に霧送り
出しダクト3hを設けたものとすればよい。There are various types of ultrasonic humidifiers 3, but for example, as shown in FIG.
The vibrator 3g may be disposed in water 3f in a water tank 3e defined by a partition plate 3d, and a mist delivery duct 3h may be provided at the top of the water tank.
なお、パルスにより電磁弁9の開く時間は1秒以内が望
ましい。Note that it is desirable that the time during which the solenoid valve 9 is opened by the pulse is within 1 second.
本考案の装置は上述した構造のもので、低温空気ととも
に加湿器3から霧が浮遊室7内へ送り込まれる。The device of the present invention has the above-described structure, and mist is sent into the floating chamber 7 from the humidifier 3 together with low-temperature air.
この霧は過冷却された水のミストであり、単に低温な空
気だけでは氷結しにくいものである。This fog is a mist of supercooled water, which is difficult to freeze with just cold air.
この霧の中へ、浮遊室内に配設した圧縮空気をパルス的
に断熱膨張して噴出せしめるエアジェツトノズル4によ
り生皮した氷晶を送り込むことによって、水と氷の水蒸
気圧差を推進力として、水滴は蒸発し、氷晶に凝縮、氷
結する。The raw ice crystals are sent into this fog by the air jet nozzle 4, which adiabatically expands compressed air placed in the floating chamber in a pulsed manner and blows out the water. evaporates, condenses into ice crystals, and freezes.
しかして浮遊室は、下部の開口部は小径であるが、上部
はど拡径ているので、下部開口部では空気の流速は比較
的大であっても上部はど流速は小となっており、したが
って、浮遊室内の霧、氷晶の滞溜時間は、氷晶を成長さ
せて、自然界で一般的に見られる程度の雪にまで拡大す
るのに十分長いものとなる。However, in a floating chamber, the opening at the bottom has a small diameter, but the diameter at the top is widened, so even though the air flow rate is relatively high at the bottom opening, the flow rate at the top is small. Therefore, the residence time of the fog and ice crystals in the floating chamber is long enough to allow the ice crystals to grow and expand to the level of snow commonly found in nature.
このようにして自然界と同様のメカニズムで成長じた雪
は、冷風装置からの上昇気流による慣性力よりも大きな
自重を持つまでに拡大すると、気流に逆らって降雪する
。Snow grows in this way using a mechanism similar to that found in nature, and when it expands to the point where it has a weight greater than the inertia caused by the updraft from the cooling device, it falls against the airflow.
なおかつ、上昇気流により一部飛散する霧と氷晶は、浮
遊室の上部開口部に設けた雪捕捉体7aの下面に捕捉、
集合することにより雪層11に長し、この成長じた雪層
を、捕捉体上面に設けたスクレーパ8により雪片状に掻
き落として降雪させる。In addition, the fog and ice crystals that are partially scattered by the rising air are captured on the lower surface of the snow trap 7a provided at the upper opening of the floating chamber.
By aggregating, the snow layer 11 becomes long, and this grown snow layer is scraped off in the shape of snowflakes by a scraper 8 provided on the upper surface of the trapping body, thereby causing snowfall.
このようにして、本考案によれば、降雪する雪は、自然
界と同様のメカニズムで成長、拡大した雪及び閃氷晶を
人工的に雪片状に成長、拡大したものであるため、自然
に近い状態で人工雪を降らすことができるものである。In this way, according to the present invention, the snow that falls is created by artificially growing and expanding snow and ice crystals into snowflake shapes that have grown and expanded using the same mechanism as in the natural world, so it is natural. It is possible to make artificial snow under similar conditions.
なお、学術的に自然界と同様のメカニズムによって生長
した雪だけが必要な場合は、雪捕捉体並びにスクレーパ
がない構造とするか、あるいはスクレーパの稼動を停止
すればよい。In addition, if only snow grown by a mechanism similar to that in the natural world is required for academic purposes, a structure without a snow catcher and a scraper may be used, or the operation of the scraper may be stopped.
