ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an artificial snow system utilized for facilities such as a skiing ground, a snow-boarding ground, and the like for which artificial snow is used.
2. Description of the Related Art
This kind of faculty for which artificial snow is used is generally housed within doors. This is because, for example, the outside air temperature is often high in regions where artificial snow needs to be used, which requires that the inside of the system is maintained at or below a given temperature to thereby prevent melting of snow.
The above system has, however, a disadvantage that building costs for a roof and the like are very high.
Further, in the above system, a snow spreader and the like are used during maintenance, thereby causing another disadvantage that special equipment for eliminating exhaust gas emitted from the snow spreader is required since the system is within doors.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an artificial snow system capable of lowering building costs.
Another object of the present invention is to provide an artificial snow system which does not need special equipment for measures against exhaust gas.
To attain the above objects, the main aspect of the present invention is a system comprising a facility for which snow is used, snow producing means for producing snow from water and supplying the snow to the facility, and means for forming an air roof by air flow so that the air roof covers space over the facility.
In the present invention, the air roof covers space over the facility for which artificial snow is used, thus making the building of a roof and the like unnecessary and lowering building costs. Further, in the present invention, the inside of the facility is opened to the fresh air by stopping the supply of air for forming the air roof, thus making special equipment for measures against exhaust gas unnecessary.
These objects and still other objects and advantages of the present invention will become apparent upon reading the following specification when taken in conjunction with the accompanying drawings.
